Photo: Circa 1910-1920
We're uncertain what year exactly this was. According to East St. Louis City Directories, in 1907 David and his father, Morris, had a shoe store. In 1912 they had a "Clothing, Shoes, and Fur" store. (Morris actually died in 1911, but his name appeared in the 1912 directory.) In 1920, it was still a clothing store, but by 1924, it had become a pawn shop. None of the directories provide a name for the store, but they appear to narrow the date of the photograph down to a period of about 10-15 years.
