I think I only bought three, maybe four, soul packs. All advertised in Black Echoes The first was reissues with a lot of dross: Bellboys, Belmonts etc. The best of this bunch was the Carlettes I'm Getting Tired which I think is a legit second issue.
The last pack I bought was mainly 70s and all originals. The pick of the bunch was Quinn Harris I'll Always Love you.
In between was the one that was the best value to me. All original Detroit including Ric Tic - Little Ann. Al Kent, a few Fantastic Four and Golden World, Adorables Barbara Mercer .etc. Nothing of tremendous value but in terms of musical quality worth every penny I paid for the pack
