In the early 1980's, I wrote several articles regarding the BOWMAN sets for the BASEBALL CARDS magazine and SCD. Shown here is a page from the 1952 Bowman FB
article which illustrates a 72-card sheet.
Zabel Brothers (Bowman's printer) used a 39-inch tract press
** to print the 1950-1952 Bowman Sports and Non-Sports cards. The printed sheets were configured with
18 cards across the sheet by "N" number of rows down the length of the sheet. This same printing process applies to the 1951 Bowman cards.
** Note
From a 1981 conversation with George Moll of the Moll Adv. Agency, which designed all the Play Ball and Bowman cards for the Bowman Company (circa 1938 - 1955).
