Issued by the Exhibit Supply Company of Chicago the 1921 edition of the cards consisted of 64 subjects with images taken from previous Exhibit issues but "updated" with a greenish tint to the photos. Due to the age of the cards and their method of distribution these cards are impossible to find in anything resembling "high grade;" just 11 examples of any card from this issue have been graded Near Mint or better by either PSA or SGC.Clearly the most popular and highly desirable card in the set is that of Babe Ruth. Featuring the Sultan of Swat having completed his swing (resulting in based on the angle of his head a popup) this example is graded PR-FR 1 by PSA due to general wear as well as some light wrinking at the top left of the card. Still a strong image this is a difficult-to-find card of the most popular player ever from one of the more attractive prewar photographic issues.Population DataPSA Population: 15 total graded 3 at this level 11 higherSGC Population: 11 total graded 2 at this level 9 higher
