Aside from the trading cards and bubblegum packs Topps did in the late seventies, they also sold single bubblegum sticks wrapped in foil with a paper wraparound displaying four different characters. They supposedly enclosed a 'movie poster pin up' although I've never seen what one looks like and they must be minuscule 'posters'. It feels a little weird collecting 36 year old bubblegum, but they look pretty cool in the display cabinet.
