Anyone recognise this stamp?

Trying to find it for a friend. I am loading it here for easy linking... but if you know what it is, I would love to get the info in a comment.

My valentine

I only made one Valentine this year. It was for a friend I thought may need a little cheer. He loved the 50's modern stuff, so I was trying to get as close as I could. Well, I guess this is more '60's, but so am I...

Remember those old mini mailboxes from Target's dollar spot? I still had all the ones I bought and never decorated them, so I thought I would give it a try. It was easier than I thought it would be - so maybe I should have tried it earlier.

I bought a whole bunch of the Fluffles stamps and decided I needed to use at least one for an Xmas card. He is the cutest little bugger. All the rest of the products are Stampin Up except the image. I am trying to use up some retired papers and colors. It seems like no matter how much I make, I don't notice a dent. Huh...
