Which department store held a Thanksgiving day parade in Philadelphia in 1920?

Contrary to popular belief, Macy's didn't host the first Thanksgiving Day parade -- that honor goes to their longtime (and now defunct) rival Gimbel Brothers (Gimbels), in Philadelphia, which started the tradition in 1920. The first parade featured 50 costumed store employees leading Santa to the retail giant's toy department. Macy's held their first parade in 1924 (tied for second in the nation with the All-American Thanksgiving Day Parade in Alaska).

Gimbels went out of business in 1987, but the parade continues under the sponsorship of a local ABC affiliate and IKEA.
