6036 Telegraph Avenue

Central Construction Co.

56th Street and Carberry Avenue

Troy Wilson

486 63d Street

This may be the mysterious “T. Wilson” of Thomas Street.

A. Nilsson

432 63d Street

A. Nilsson did this whole lot’s sidewalk, running around the corner onto Dana Street, where he marked the other end with the initials “AN”.

Avelar & Co.

818 52d Avenue

A better example than the first one I documented.

Andrade & Moniz

815 52d Avenue

Andrade (without Moniz) also used this escutcheon, but so far I haven’t found one with a date.

P. P. & D. Co.
