O.T. Frasch Images 520-529

We know of one possible O.T. Frasch image in the range from 520 to 529. It is unsigned and shows "Gibraelter Rock", which is apparently a feature on Mt. Rainier named Gibraltar Rock. The writing of the caption looks very much like Otto's but there are not enough distinctive features in it to be certain.
