1975 marked the first foray into baseball card issues from the Hostess company. Consisting of 50 different three-card panels that formed the bottoms of boxes of snack cake products the cards were widely collected in their day and Hostess would issue cards on their box bottoms for four more years as a result. Reportedly tested in select west coast markets only the more scarce Hostess Twinkies cards contained one card per package with an emphasis on west coast players. The Twinkies set was comprised of just 60 cards as opposed to the 150-card standard Hostess set with each card identical to its regular Hostess products. They are more scarce than their counterparts and are typically fraught with condition issues since they were distributed inside the packages.Presented here is a "progressive" proof sheet containing the entire 60 card set on a single sheet. Typically progressive proof sheets number five sheets with one sheet for each color in the four-color printing process plus a fifth full-color sheet. In the case of this sheet however the four colors are all represented on one single sheet but not printed together on the individual cards. The result makes for an interesting display. More interesting is the fact that the set is loaded with superstars and Hall of Famers: Don Sutton Willie McCovey Robin Yount (RC) Hank Aaron Joe Morgan Lou Brock Pete Rose Rollie Fingers and Nolan Ryan are all represented here.The sheet itself is in apparent VG condition with a large but difficult to see crease down the center ostensibly where the sheet was once folded. There is edge wear consistent with it"s age and the card reverses printed in black are all apparent. The sheet in its entirety measures 32 3/4 x 25". An outstanding piece and an interesting display from a less common test issue from the 1970s.
