Hello Fellow Collectors. Thought I throw is some "Childhood" memories for my youth. These cups/mugs were produce in 1966 but National Periodical Publications. Both cups look identical, until you tip them up...one has semi see-thru sticker of Batman, the other of Robin. These are copyrighted items of NPP. Ran out of photo spacings or would have added another photo of far side of Outer Sticker. Photo #2 shows Robin at the "B" other side has Batman at the "N".
Thanks for looking and ZONK.....ZAP..... POW to all the older Batman fans from the TV Series.
