1975 Topps packs - who remembers?
 

Buying a pack and seeing on the wax package, buy a 1975 Topps set for $14.95 plus $3.95 postage and handling (may have been $17.95). Or send in 10 wax pack labels and get an uncut sheet of team cards for $2.95 + $1.95 shipping.

I got an uncut sheet from the advertisement.

Me too, but sold it years later! Should've bought the set. I remember the 3 pack cello's for $1.25.
