50 & 52 Third Avenue | Block : 556-1 | Lot #26 Building Date : Mid-19th c./1991 alt. Original Use : Commercial/Residential Original Owner : Unknown Original Architect : Unknown Description & Building Alterations This three-story conjoined building was once two separate buildings. Today there are still two separate storefronts. The buildings were likely constructed in the 19th century, but their facades have been given a complete 20th century makeover. From the late 19th century until sometime in the 1960’s, a store called Sig Klein’s Fat Men’s Shop existed in the northern storefront. As evidenced by the tax photo, around the 1930’s and 40’s Stuyvesant Loan Office was housed in the southern storefront.
