During each month from June through September 1952, the children's magazine Shonen Shojo Boken Oh issued an uncut strip of three large baseball cards bound into the magazine. A total of 12 different cards were produced. The cards are very rarely seen today, and Japanese Baseball Cards Checklist & Price Guide, Vintage Edition 3.0 has assigned a scarcity factor of R5 to the issue, indicating that five or fewer copies of each card are known to exist today.

This panel includes cards of three of the top pitchers of the era. They are (left to right) Tokuji Kawasaki, Shigeru Sugishita (HOF) who won 32 games that season, and the immortal Masaichi Kaneda (HOF). Kaneda was in only his third season in Japan Pro Baseball, and was still a bit wild, as he led the Central League in both strikeouts and walks in 1952, before going on to win 400 career games.

The panel is blank backed.

Size: Panel--10 1/2" x 5 7/8". Each card--3 5/16" x 5 7/8"

Condition: There is a crease at upper right of the Kaneda card, only slightly affecting the image. Otherwise, Vg/Ex.
