8.5x11" illustrated blister card contains 2.5x2.75x1.25" deep battery-operated "7 Transistor Precision-Built Model BAT-7" radio. ©1966 NPP, Inc. Topp produced another similar Batman transistor radio, but it was slightly smaller and came boxed, not carded like this larger version. Radio has "Batman Secret Micro Radio" brushed metal insert on front top edge. Radio also comes w/earphone and original battery (w/no leaks). Card shows some aging and minor surface paper lifting along lower left corner of blister, but rest of blister remains firmly affixed to card. Tiny ding at hanger hole. Fine overall. Radio has some aged tape strips on side, securing plastic overlay as originally packaged. Mint as packaged. Very rare, we know of only one other example still sealed on its original card. As rare as the boxed example is, this carded version is much rarer.
