Blue-tinted version of Rogers Hornsby's 1926-29 Exhibit card, picturing him with the Cubs.  The fact that Hornsby only began his Chicago career in the final year of this Exhibit style's run would lead one to believe this version of the card must be more scarce; grading company population reports might suggest otherwise, as Hornsby was actually with three different teams during the 1926-29 period.  PSA has graded 26 "Chicago" Hornsby cards from this issue, 21 Boston (where Hornsby was in 1928), and just 11 St. Louis.
