I'm laughing over here, but wow.
Cracked me up, too ... It’s a creepy Stalinist insult even BEFORE you open it. WHAT were they thinking???
The way you're thinking, no. It was a large, glossy post card, with a photoshopped manila envelope one one side (even the stamps and cancellation marks were part of the 'shop) with the other side again, a photoshop of an open envelope revealing the computer-generated 'report card'.
There was a television evangelist out of Dallas that used to send out a brochure that to the casual eye appeared to be an amateurish self-published mailing with ball point pen and sharpie writing all over it. Upon closer examination it was an expensively-produced direct mail marketing campaign. The union printer's imprimatur was all that gave it away!
