The wording of the entire back of the card is a bit confusing, as it perhaps would to a Brit with only a cursory understanding of the American game.

"C.H." Sisler - C instead of G for George?
41,979 - instead of .41979 as we write it

Sisler hit .41979 in 1922. The Senators were rapidly improving with Walter Johnson (eventually winning the 1924 WS and losing the 1925 WS) and gathering larger and larger crowds due to stars like Babe Ruth and Sisler (who did not play in 1923) visiting D.C.

So taken as such, "$100,000 Base Ball Monument" could be taken from a contemporary news story about Clark Griffith's plans to greatly expand what was then National Park and renaming it Griffith Stadium due to the rising attendance.

Perhaps there was a contemporary news article that mentioned the original plans of the expansion to include the names of the A.L.'s biggest stars on a monument... or on the stadium itself?

Why didn't Sisler play in1923? Injury?
