That is one very neat jersey. I think this BST post should get carried over to the memorabilia side so that more eyes can see it and some of the heavy hitters can weigh in. After looking at all the Steinfeldt cards that have photos at vcp.com and other limited resources at my disposal such as the LOC on-line it looks like his T206 "With Bat" is your best bet for a card match to your jersey. I got these 1910 Spalding Guide pages from the LOC and, although they do depict the 1909 road uniforms complete with pinstriping, unfortunately Steinfeldt's image is such that the logo etc is turned away from Conlon's camera. You can, however, see the dark (is it black or navy blue?) sleeve piping which seems to be indicative of the road jersey.
