I’m not particularly choosy when it comes to collecting and adoring postcards. I love many types and genres and from any destination. But items have to be a proper postcard.
Here’s a sample of a recent postcard below that stretches the boundaries of a postcard versus cool envelope.

It is an example of a foldout postcard in that it is one large sheet of paper that has been folded into three components that fold into one standard size postcard for mailing.
Here’s the interior component with a message:

Postcard message:
“Hi Glen. I got this in the mail. It came in an envelope, however it does have space for a stamp in the back. Maybe it was originally intended to be sent with no envelope?
In any case, I removed the original message (a simple thank you for a referal) and sent it to you. Hopefully, this can find a place in your collection. If not, let me know and I’ll send you another cool postcard as soon as I find one.”
Below is the back side of the postcard – with another message and stamp (making it a postcard):

Postcard message:
“Hi Glen. Not sure if this counts. But I did write you a message inside.”
This does meet my definition of a postcard – very happy to add it to the Collection!
