I very knowledgeable board member and postcard collector contacted me because he thought this may be a photo of the University of Chicago team playing Waseda University in Japan. This happened a number of time - you can read about it here:

Though Faber's uniform (below left) is very similar to that of the guy in the postcard (below center) - the font is actually different. This is most easily seen when comparing the cross-bars in the respective letter H's. For Faber - it is clearly at an angle, for the postcard guy, it is straight across.
Below right is a photo of a U of Chicago player (Glen Roberts). The lettering on his jersey does seem to match that of the postcard guy. While he has a collar and the postcard guy does not, we found other U of Chicago player photos from the 1910 tour with that same lettering font and no collars. A translation of the Japanese writing may confirm this is U of Chicago vs. Waseda.
