Find of the day. Photos are front and back (I just flipped them over). Pretty interesting history I found online:
http://www.stamp-collecting-world.c...ngcards.htmlWonder about the value? Anyone care to venture a guess?
The R13 has a circular cancel, all I can make out is JUN (which should mean June?). The 2 R15's have what look like smudges which look like some kind of cancel and should be visible in the photo,
Thoughts?
Thanks!
Dave
