>>>On the front is a black-and-white illustration of a stag near a frozen lake with the words “The Challenge” in the lower left corner.<<<
Thanks for finding!
Must’ve been something only they knew. Maybe the card was sent with just one of the item in question.
Thank you for clearing up that mystery. Was also wanting to know what the picture was on the obverse. I used to collect postcards in my youth because they were inexpensive, and the vintage ones have nice artwork.
I’m going to guess that the person wanted a pair of these postcards. The one the writer couldn’t get might’ve been a similarly themed picture by the same artist. Maybe wildlife from Canada or northern Europe was of interest. Of course, it could be a pair of something mentioned in a letter or in their last conversation. The mystery lives on. :)
