During the 1966 Batman TV Series the Topps Trading Card Company went nuts releasing many different '66 Batman Card Sets. Here are some photos of one of the wrappers & store display boxes. The last photo is an example of a special packaging they used to sell multiple cards of the "color photo" series. They were sold in a hanging bag with header card. These "hangers" are extremely RARE! Our photo here shows both the front & back.
