So far I've only been able to find two pre-1968 promotional albums issued by Motown that have promo labels or promo text added to the labels and not just a "Disc Jockey Copy" or "Promotional Copy" stamp on the cover.

Are there any others? I've heard that a promo of the first Marvin Gaye album exists with the same style promo-label as the Gospel Stars, but I've never seen it, and it's a difficult topic to research with how many people mistake the early white Tamla label as a promo.

Thanks!
