1963 Fleer #26 Ralph Terry (Yankees)

Similar to the early 1900's Mecca Double Folders, these colorful 2-1/16" x 4-7/8" cards are actually 2-cards-in-1 ! Perforated in the center, you can fold to create cards of 2 different players. Unperforated 1955 Topps DoubleHeaders exist. All 132 players (66 cards) in the 1955 Topps DoubleHeaders set were also in the regular 1955 Topps set, with the same action image.
NOTE: Laid side-by-side the cards form spectacular scenes from actual stadiums !!!
Old-timers - can you identify the stadiums ?

ROOKIES:
  Harmon Killebrew, Hal Newhouser
STARS:
  Ted Williams, Hank Aaron, Jackie Robinson ...

The 1969 Topps Stamps set contained (240) 1x1-7/16 inch stamps. Stamps were released in both horizontal & vertical panels with the player's name in a banner. 1974 Stamps, the name was inside an oval.
Topps issued a mini albums to hold complete 10-stamp team sets and the back cover had facsimile autographs of each players.

The 1969 Topps Stamps set is packed with stars: Pete Rose, and Mickey Mantle, Willie Mays, Roberto Clemente & more !!!

"Baseball Action Stickers" were STAR-PACKED 3-panel sticker strips, some with facsimile autographs. There were (16) different strips in the set but only 12 are totally different. #13 thru #16 re-used panels from #1 thru #12.

Strips were perforated, folded at joints and put in packs. Boxes had 12 packs (10 cents each) with 1 sticker per pack. Sets could be made back then for $1.60. Today, the Mantle panel goes for around $2,000.

Collectors often collect just individual panels as complete strips are so scarce, fragile & EXPENSIVE. Single panels themselves are quite scarce - in 20+ years PSA has graded just over 200 TOTAL compared to over 1,000 1952 Mantles !!!

PROOF sheet below is missing the facsimile autographs.
