Charles P. Lazarus founded Children's Supermart (which would evolve into Toys "R" Us) in Washington, D. C. , during the post-war baby boom era in April 1948 as a baby-furniture retailer. Lazarus, who served in the Army during World War II, opened the first store at 2461 18th St. NW, where the nightclub Madam's Organ Blues Bar is. He began receiving requests from customers for baby toys. After adding baby toys, he got requests for toys for older children. The focus of the store changed in June 1957, and the first Toys "R" Us, dedicated exclusively to toys rather than furniture, was opened by Lazarus in Rockville, Maryland. Lazarus also designed and stylized the Toys "R" Us logo, which a featured backwards "R" to give the impression that a child wrote it. It was acquired in 1966 by Interstate Department Stores, Inc. , owner of the White Front, Topps Chains and Children's Bargain Town USA, a toy-store chain related to Toys "R" Us in the American Midwest that would later be combined with the rest of the Toys "R" Us chain. The original Toys "R" Us store design from 1969 to 1989 consisted of vertical rainbow stripes and a brown roof with a front entrance and side exit.
