Capitol Capeman has the solution for the tapes that clutter your living room, and his tapes are superior too! Classic Neal Addams ad for music retailer trade mags (although the jury is still out as to where this ad actually appeared).
update – People in the know have revealed that Stak-paks were marketed between Summer 1972 to Winter 1973/4, and that this particular ad also appears in the Neal Adams Treasury Volume 2 (1979).  The jury is out on whether it ran in National Lampoon.
