NAP Plaques was a fun, late 60's, 6 x 9 cardboard novelty sign item for use in your home or office. Online research reveals that ace artist Vic Cantone and North American Publishing Corp produced a huge, various assortment of them back in the day, (all cheeky middle fingers aimed at the "the man", "the establishment" etc.) Here are 9 examples I found at an antique mall last week. To see more just Google "Nap Plaques", and also check ebay-- where of course prices seem crazily steep-- I only paid $1 each for these, while some are priced at $35 a pop?!
