During a recent trip at the flea market I managed to find the late 1970s Pocket Heroes version of the Batmobile released by Mego. Its in almost perfect condition, with only the stickers and plastic "glass" window missing. I got it for extremely cheap! I've seen this going for around $90 on Ebay. Here it is in all its glory!
Here is the original box as I remember it when I got back in the late 1970s! Also thanks to the great Mego Museum web site, here are some images of the vehicles and figures. I remember playing with these! Now I need to find them again.
