Worn but Unmistakable
There are many intersection in Queens where a well worn access cover is present, but with any identification script long worn away. They are often still identifiable however by the distinctive pattern of vent holes, most easily seen as groups of 3 hole triangles circling a pair of holes in the center. The pattern of the ubiquitous BSBQ covers of the Bureau of Sewers Borough of Queens.
The 16 - 8 - 2 design of the vent holes seems alost certainly to be from the BSBQ covers, or their successor DPW covers. The only question is is this the worn top of the covers or the bottoms of the covers subject to long wearing. A close look at the position of the pry hole on the edge as it aligns to the two center vent holes. More research is necessary!
Throughout Queens, especially in the Northern and Western areas.
