Thanks for the excellent observations and input so far! (More is always welcome.)
The thing to bear in mind with illustrations, though, as contrasted with photographs, is of course
their often questionable accuracy. Is the drawing absolutely faithful to the reality of actual equipment
or uniforms or what-have-you? Is it just an approximation or artistic "shorthand"? Just within
our own tiny backwater collecting niche of sports boardgames, we could show you several items
that look very much of the 1870s-1890s timeframe (and are frequently ascribed to that period)
but have been proven indisputably to come from the 1910s or '20s.
Often the best that can be said is that "well, this kind of looks a lot like something that wasn't around
until (such-and-such) year, so it can't be older than that."
Here's the entire box lid and the interior gameboard -- even more sports gear! The conformation of
the various lacrosse sticks, tennis racquets, golf clubs, and so forth drawn there might also be telling,
but the catcher's mask was the one item that really jumped out at us.
This isn't ours, unfortunately, but it's a recent acquisition by a member of our own Forum,
on whose behalf we're inquiring...
