Very excited to add these:
1967 Caprolan Nylon premiums. Gino had an endorsement deal with them and was one of the 10 players in the set. The premiums were distributed in a nylon sleeve with a glossy 8x10 b&w photo and a separate, larger sheet of paper with a bio of the player. The bio sheet is huge, so I cropped it a lot so that hopefully you can read the text. Astute observers will notice this is the same photo used on his rookie card.
So how rare is this? My go-to guy to purchase and learn about oddball issues is Mike Mosier at Columbia City Collectibles. He says that in the past 30 years he's only seen 2 Caprolan Gino photos and the other one was trimmed, ripped and water stained and came without the separate bio.
In case you're curious what the sleeve looked like, here is the photo from the listing:
