Red Ball sales co in 1936 put out a set of 16 mini pennants now cataloged as bf3s. Apparently they came with gum because for 15 cents and 25 gum wrappers you could send in and get one of the 16 in a 28 inch premium size.
Below is a counter top diplay of the 16 plus the Red Ball offer. I have also included pictures of 12 of the 16 premium sized pennants. They are quite rare and sell in the one to three hundred dollar range.
