 White Sox player Bill "Bullfrog" Dietrich is mentioned as being  traded. He was traded to the White Sox in 1936 and from the White  Sox in 1946. Since the family drives a 1937 Olds, it would imply it  was the 1946 trade. This would be consistent with the soldiers  present at Higbees corner window in the movie opening since the war  may have just ended. However, war era versions of the decoder badge  were paper due to the shortage and Little Orphan Annie was off the  air well before 1946.
