1998 SPx Finite Spectrum #225 Mark McGwire PP

Neat oddball set with a very unusual mix of players. A promotional lead-in for "Cardboard Dreams" a soon to be sportscard magazine. Promo cards were given out at a few regional baseball card shows mostly in So. Cal.
MLB filed lawsuits against similar magazines and the magazine was cancelled before 1st issue leaving just a small run of promo cards (limited to 5,000) and some scarce proofs.

Without a doubt my FAVORITE SET - PERIOD. Regular issue, test issues, inserts ... whatever ... this is # 1 !!!

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 ...

1960 & 1961 Fleer baseball card sets of old-timers like Babe Ruth bombed. Kids wanted Willie Mays & Mickey Mantle. Topps had rights to baseball cards & gum so Fleer tried something new ... COOKIES !!!
Cherry flavored cookies with 1963 baseball cards.
1963 Fleer baseball card set was cut short at 66 cards & checklist by Topps lawsuit. But what 66 cards! Attractive & packed: Clemente,Koufax... & 2 very scare Short Prints.
Maury Wills 'rookie' card is a story. Majors in 1959, quickly superstar. But 1963 for rookie ??? In 1959 Topps deemed Wills NOT WORTHY.

Wills was upset. After 1962 MVP, Topps came knocking but he said "NO!". Finally, 1967, Wills first Topps & most costly card. Note: 1961 Post Cereal card, years BEFORE 'official' rookie. He also photo-bombed a 1960 Topps card.

Disclaimer: Above mostly true - but Wills has said "no feud".
