WHAM-O MINI FRISBEE
SECOND PERIOD PREMIUMS
Glitterfoil was the product used for hot stamping. These may have been prototype runs to figure out how to get advertising onto a Mini. The 3rd period Minis solved that problem by eliminating the cupola and lettering from the top side.
The blue Frisby Manufacturing Mini might look like a 1st period, but you can see the flight rings under the label.
The Cool 'n Creamy Minis were made from the Wham-O mold, but with all reference to Wham-O and Frisbee removed.
