Here is a vintage WHEATIES Braniff Airways Conquistador International UNUSED Luggage Label Sticker.   It is 3.75 inches tall and 3 inches wide.  I noted this as used, but it does not look like the sticker was placed on baggage.    It does have a crease in the middle, presumably it had that when new.    Otherwise, it is in very nice condition.   Please see pictures.   I will ship in an ebay envelope.   Thanks for looking.
