These are not Postcards that have an image of a toy or game, but rather, postcards that ARE the actual toy, game or activity.
For example, postcards that transform into a toy or a puzzle, or can be colored, contain a crossword, etc.
Some images to illustrate the examples:
Here’s my first registered Toy Postcard:
I also created a Maxipic with it:
Hope you guys like it
A good friend bought me these. They go into my personal collection still untouched. A very unique card. I wouldn’t dare to send it via normal post though.
They have the shape of elephant too
They also have bookmark and keychain that you can send as postcard and then take off to be used as bookmark and keychain
I also made this Shaker Card for the celebration of our Postcrossing Indonesia Community Birthday
Sadly I think the card never arrived
I have these two cards, out of which you can make a moose and an owl respectively. They are made of very thin, almost flimsy wood, but I sent a similar one to Germany (without an envelope) and it arrived unharmed.
Awesome!! Do you have the link to the one you sent?
No, it was not a Postcrossing card.
