Thrift: Ritz Cracker Box Envelope

 Most cardboard packages make good postcards, 

but this one cries out to be a cover. 

With a slogan like Open for fun, there should definitely be an envelope template printed on the inside of the box. 

I can't be the only one who thinks so, can I?

Now it's peeking at me!

(I don't play with my food, just the packaging.)
