This is a used race program for Yellow Jacket speedway. There is no date but I believe it is from 1946, there is a ad inside for 1946 Hudson car. Yellow Jacket speedway was located at Erie Ave and G street in Philadelphia. It opened in 1938 as 1/5th mile dirt oval. In 1939 they paved the track. In 1942 the track was closed because of world war 2. During these years they raced midgets. After the war they reopened in 1946 racing stock cars and closed for good in 1950. Land had become to valuable. This is in decent shape, except the back cover is missing. Free shipping in the U.S.
