The first set represents the inaugural Hostess entry in the baseball card market and was issued during the 1975 season. This is the much scarcer Hostess Twinkies pack insert version as opposed to the standard 1975 Hostess set which was found on the bottom of Hostess boxes. Due to these panels being issued in a cellophane wrapper along with the Twinkies cakes, almost all cards will exhibit staining. Complete set of 60. Among the key Hall of Famers in this set are: Robin Yount (Rookie Card), Joe Morgan, Don Sutton, Willie McCovey, Lou Brock, Rollie Fingers, Nolan Ryan and Hank Aaron. All are full, untrimmed 3x4.25" panels. Aside from the obvious and always present staining (much of which is on the blank margins), average condition of the cards are EX. The second set is from 1976. 150 2.25x3.25" cards, all very neatly trimmed as intended from three-card box panels. Key HOF cards included: Joe Morgan, Phil Niekro, Gaylord Perry, Lou Brock, Robin Yount, Johnny Bench, Rod Carew, Tom Seaver, Brooks Robinson, Willie Stargell, Jim Palmer, Carlton Fisk, Nolan Ryan, Dave Winfield, Mike Schmidt, Tony Perez, Hank Aaron, Rollie Fingers, George Brett, Willie McCovey, Jim Rice, Dennis Eckersley (Rookie Card), Jim Hunter, Reggie Jackson, Carl Yastrzemski and more. These cards were meticulously removed w/extreme care and the set presents as NM-Mint w/almost all black dotted lines visible around the edges of the cards. The presence of these black lines is key to having these cards graded by a third-party authenticator should the winner of this lot choose to do so.
