I ran across the following promo for the 1993 Yoo-Hoo Baseball Legends set in the Summer 1993 issue of Topps Magazine. Berra had a promotional relationship with Yoo-Hoo dating back to the ’50s.
The ad covers most of the set’s basics, but after some research, there’s no difference between the design of the two series cards. However, the Standard Catalog says Series 1 had Yogi Berra, Joe Morgan, Duke Snider, Steve Garvey, Jim Rice, Bob Feller, Pete Rose, Rod Carew, Gaylord Perry, and Graig Nettles while Series 2 had Johny Bench, Lou Brock, Stan Musial, Willie McCovey, White Ford, Phil Rizzuto, Tom Seaver, Willie Stargell, Brooks Robinson, and Al Kaline.
There was another ’90s Yoo-Hoo set issued in conjunction with Rawlings in 1994.
Rawlings sponsored the Gold Glove award, so the set features past winners. The set is relatively common, but apparently, Yaz signed a few copies that were randomly inserted, though I haven’t found a copy, and apparently, they weren’t certified on the card in any way. BaseballCardPedia wrote that the 1994 set was released in two, 10-card series consisting of eight player cards and two fact cards which is backed up by this piece I found on eBay.
Also, note that since the set’s weren’t licensed so all the team logos were airbrushed out.
