Reach Official American League (Barnard) baseball, dating to 1929-31, signed in steel tip fountain pen by the "Big Train."  Largely clean with some minor surface abrasions here and there, the baseball has been well-preserved.  The signature was applied in dark blue ink, somewhat faded but still quite attractive. Surface abrasions have marred a bit of the handwriting in Johnson's last name, but the signature remains legible.

Johnson single-signed baseballs are quite difficult, their profile elevated due to the exciting sale of a particularly strong example for $315,000 in the spring of 2023. Since then, the value and scarcity of such artifacts have attracted considerable attention among hobbyists, with even faded signatures on unofficial baseballs reaching well into the five figures.  The six-figure signature was also applied on a Barnard baseball, a remarkable example in its original box.  With single-signed baseballs of deadball era Hall of Famers in extremely high demand, players don't get much better than Walter Johnson, perhaps the greatest pitcher of all time and certainly one of the most coveted autographs of his era.  Full LOA from James Spence Authentication.
