I found this and another similar at my dad's house. It has an Eatons label on the back. His grandfather was an avid collector so I'm thinking this came from him. I have no idea what it is, if it's valuable or its history. Can anyone help?
I would guess that these cards were your dad's notecards for family, friends, and associates, to be sent on special occasions...congratulations, etc.
The scenes on the 2 cards look to be non-specific, from a historical and cultural standpoint. Eatons surely communicated what they wanted to the artist/designer, so that the cards would be useful to a wider slice of the public.
They appear to be laminated by Eatons for display and have an Eatons label on the back of the board with hangers. I did notice after posting these that they are signed and dated, one in 1945, the other in 1932. I'll keep searching.
