WIYM: Hmm, That's Different! #2

For this swap we will be sending or one partner a store bought postcard that's got a unique component... something PHYSICALLY different.

Is there a hole in the card by design?

does it have a weird shape?

Is it 'see thru' in some place?

Does it have a glow-in-the-dark component?

Is it lenticular (google the definition)

does it make a puzzle?

Anything about the way the postcard was made that makes it different from mainstream postcards.

Sender's choice

Send blank OR written you must post below in comments before partners are assigned or you will simply get what your partner decides.
