Manhole covers in New York City

Registration No. 2148415447

caryfukThe circular metal grating is set into a pavement of hexagonal concrete slabs that show signs of wear and cracks. The central leaf emblem, surrounded by radial slits, bears the inscriptions 'CITY OF NEW YORK' and 'PARKS & RECREATION', suggesting its municipal origins and function within a recreation zone. This example, as the Institute of Lidology would note, is a typical example of urban infrastructure where aesthetics give way to functionality, but with a certain hallmark of local identity.

caryfukOn the asphalt surface, interwoven with white road markings, a circular metal artifact is located. Its surface is marked by corrosion and exhibits a radial geometric pattern, which could be the subject of deeper lidological analysis. A central point with a rivet indicates a robust structural solution for drainage, a detail that the Institute of Lidology carefully catalogs.

Registration No. 2439679208

caryfukThe circular metal structure, set in a pavement of stone blocks, shows signs of wear, indicating its long exposure to urban traffic. The central section is perforated with a series of triangular and circular holes that could be used for ventilation or as handholds for handling. The inscription around the perimeter, though partially eroded, provides a key to identifying its original purpose, always a fascinating discovery for the Institute of Humanology.

caryfukA complex geometric pattern with many circular elements dominates this example of urban infrastructure. The central inscription 'EDISON CO.' indicates its historical affiliation with early electrical networks, making it a fascinating artifact for the Institute of Lidology. Its robust cast-iron construction is set into a paving of small cobblestones, testifying to its longevity in the urban environment.

Registration No. 9061184230

caryfukIn the center of the perforated surface is a prominent logo with the letter 'U' and the inscription 'ConEdison'. A circular pattern with tiny holes spreads around the center, surrounded by a rusty, geometric ornament that gives this specimen an industrial character. The edges of the manhole cover are lined with cracked pavement made of various types of paving stones.

Registration No. 6437221807

caryfukA circular grate with a repeating pattern resembling gears dominates this example of urban infrastructure. In the central part, alphanumeric characters "E.S.C.", "G.T." and the number "8" are visible, indicating a specific classification. The surface shows signs of significant wear and patina, testifying to its long-term exposure to the elements.

Registration No. 8980717560

caryfukA round metal artifact, embedded in a grey sidewalk, exhibits an intricate grid pattern with a central circular emblem bearing the inscription 'N.Y.C.S.'. The surface of this specimen, interspersed with regular holes, bears clear signs of wear, testifying to its long-term exposure to the urban environment and the relentless passage of time.

Registration No. 1106199500

caryfukA sturdy circular pattern with rayed triangles surrounds a central disc bearing the inscription "ATLANTA W.P.D." around its perimeter. This urban artefact, an exemplar of municipal infrastructure, is set in a heavily cracked asphalt surface, intersected by worn white road signs. Its weathered appearance testifies to years of faithful service.

Registration No. 3366190532

caryfukOn the surface of the dark asphalt is a circular cast-iron disc whose embossed inscription 'BORO MANHATTAN NY' clearly identifies its origin. This example of urban infrastructure exhibits a radial arrangement of triangular segments, a design element that seems to effectively combine aesthetics with functionality. The presence of small openings suggests its role in the drainage system, an area that the Institute of Lidology has studied with unflagging interest.

Registration No. 4424530583

caryfukCircular grille with distinctive geometric pattern and inscriptions "N.Y.C. SEWER" and "MADE IN INDIA" dominate the asphalt surface. Clearly cast in iron, this specimen shows signs of normal wear, but its functional integrity remains intact, which is crucial for the study of urban infrastructure. The Institute of Lidology would appreciate clear identification of the SIGMA manufacturer and country of origin, which contributes to an understanding of global supply chains.

caryfukThe rough, uneven texture of the surface of this example of the cast iron hatch indicates considerable wear and corrosion processes that have affected it over time. The rim is flanked by a simple, slightly raised ring which shows illegible white marks, probably chalk or paint residue, and the very faint numeral '262' on the base. Set in a grey concrete pavement, this artefact is a fascinating study of the interaction of urban infrastructure with the elements, an area that the Institute of Humanology is keen to explore.
