RMY is rather full of it on this one; they claim that this is "the only image of Otis we have ever seen in the hobby", completely ignoring the multiple shots of Otis at Hilltop Park in New York from later in September of 1909 that
tnfoto posted earlier in the thread.
Still, this picture (taken by the
Cleveland Plain Dealer on September 2nd 1909, before the Naps went on their season-ending 24-game circuit of the other seven ballparks) is nice and is probably the only one of Otis in the Cleveland home uniform, so there's that.
(usual debrowning and tweaking and such)
