I bought a few, probably the best (now) were Shelley Fisher - Girl I Love you (Dalya) and Dickie Wonder - Nobody Knows (Golden Triangle), but I didn't really appreciate them until years later!
The packs had a lot of the less rare Ric Tic and Golden World sides, plus quite a lot of 70s stuff which was too modern/ disco for my tastes at the time.
Gave up buying them as was getting doublers - things like Voices of East Harlem- Cashing in, Jesse Fisher - You're not loving a beginner etc! Often wish now I had bought more.
