1956 Topps FLAGS of the World #18 CHINA Nationalist

1952 is often thought of as Topps 1st baseball card set, but it was not.
Topps issued several smaller baseball card sets prior to their huge 1952 set.
Topps buzz word was "BIGGER is BETTER" for their 1952 Topps set which Topps described as: "GIANT IN BOTH SIZE and NUMBER of CARDS" (407).

Key card in the 1952 Topps set is #311 MICKEY MANTLE. Often called Mickey Mantle's Rookie card - BUT IT IS NOT. That honor goes to his 1951 Bowman.
1952 Topps "High Numbers" (#311-#407), are very, very scarce with an interesting story:
This HUGE set was released in series weeks apart. By the last (6th) series, baseball season was over and football starting. Candy shops had plenty of baseball cards from earlier series so most cancelled their orders for the last series creating the scarcity.

Adding interest is how Topps disposed of the now un-needed cards including THOUSANDS of 1952 Topps MICKEY MANTLE's. They dumped them into the Atlantic Ocean like most of New York's trash in those days.

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 ...

There is one card for each NFL team in the 1976 Popsicle football card set PLUS a variation of the New York Giants. The Giants changed logos in 1976, but Popsicle didn't know so one card shows team's 1975 helmet and the corrected shows the 1976 helmet.

The cards are like thin plastic credit cards and held up well as apparently they came one per box of Popsicles.
