Interesting 1906 Cyanotype Postcard from Camp Red Wedge, with Gingerale Drawing

So much information packed into the face of this 1906 postcard, sent by "Red" from Camp Red Wedge, West Virginia to "Friend Dr." John Montgomery in Chambersburg, PA, who was clearly busy since arriving at the camp the prior evening at 10pm.  In addition to this wonderful image of two young men the canoe landing, most urgent seems to be Red's request that that doctor order him photo supplies for making more cyanotypes! Plus a little drawing of a bottle of gingerale. Quite an evocative thing!

3 1/2" x 5 1/2" and in very good condition.
