What you are suggesting does not fit with the timeline of when these cards were produced; and, when
Elberfeld was traded to Washington.
The NY version of Elberfeld is in the 1st series (150) and was printed in early 1909. Subsequently, when
the 350-only series was printed in early 1910, Elberfeld had been traded (Dec 16, 1909) to Washington.
Shown here are three of my Elberfeld (NY) cards....notice those marks do not normally exist on his shirt.
The marks that you pointed out on that one particular card are extraneous (and not hints of the "W".....
they don't even line up where the top tips of the "W" should be on his shirt).
