First up, the 1990 Publications International Hottest Players Angels Team Set.
Two stickers in the team set.
These blank back, oversized, no-numbered stickers (4-1/8" x 5-7/16") were sold 4 per sheet (I assume you had to cut them out - hence the bad crop on the Joyner) and were sold with a 36-page sticker album. The design is very similar to typical early 1990's designs...full bleed, bordered, colored bands.
Another set issued was the Hottest Rookie Stars.
Two stickers again for the Angels.
These were sold four per sheet in complete sets which included the album.
It wasn't worded as such but I think the Hottest Players came as a complete set as well.
Here's the size comparison to a standard sized baseball card.
Nice little oddball 90's offering.
