In 1951 a similar style was used, hand-painted colour reproductions of black and white photographs, some of the 1950 images were reused on the 1951 card set. But Bowman increased the size of the cards to 5.2cm x 7.9cm ( 2-1/16in by 3-1/8in) and increased the number of cards to 324. This was the biggest set of baseball cards at the time.
In 1950 Bowman had a monopoly, but in 1951 Topps entered the baseball card market with their 52 card blue back, 52 card red back playing card game.
The two most desired cards from the 1951 Bowman set are the rookie cards of Mickey Mantle #253 and Willie Mays #305, both of which are horizontal cards. Mantle wasn't included in the 1951 Topps set, he had to wait until the following year for his Topps debut. Some notable omissions from the 1951 set were Joe DiMaggio, Stan Musial and Jackie Robinson.
I really like the Bowman sets from the 1950's. With some fear of being shunned by the baseball collecting fraternity, I prefer the Bowman cards over the Topps from this era. That is until 1955 when Bowman ceased to produced baseball cards.
