About Baseball Weird-Ohs (Base Set)
Fleer used the "Weird-oh" designs created by the Hawk Model Company to poke fun at baseball. This is simular to the regular Weird-Oh's cards released the year before (1965).
Note: Stickers with fronts identical to the cards have been reported. They may have been inserted in packs but more than likely they were put inside the Weird-Oh models as a marketing move.
