Strange Air Mail Cover With Even Stranger Drawing Inside!!

Anyone have any idea what exactly this could be? And shouldn't there be a received stamp on the back? Part of it appears to be burned. Possibly from a crash? Not sure just throwing out suggestions!

Self-made postal history... with a strange twist.

Oh ok thanks! Strange indeed

Yikes, an atomic bomb drawing.
Indeed, this was part of growing up in the 1960s and early 1970s. I know kids today have to fear mass shootings but back then we had atomic 'duck and cover' drills in school where we were taught to 'hide' under our school desks and not look into the blinding light of the atomic bomb. Those that could afford it, dug bunkers into their backyards. Being I was young and dumb, I sewed peace symbol patches on the army jacket I purchased at the second hand store along with various other 'hippie' patches. I was strongly left leaning back then and joined protests against the war. When US pulled out and left behind all the people that had helped us in South Vietnam I learned an important life lesson.

I wonder if that is still a feature with the current house at that address.

The envelope never went through the mail - note the complete absence of postmarks on either side.
It is not postal history - one could make up a very similar envelope today using old stamps.

The Blue Chip and S&H Green Stamps are a nice touch.

DUCK & COVER DRILLS! Boy, does that bring back memories of stupid school films and school air raid drills! Don't throw it out. It is a unique part of American history.

Cool thanks everyone for the feedback! I figured it hadn't been used through the mail service. I still find it to be cool and will definitely hang on to it!

Did it come with a tin foil hat?

Nah, you didn't need a tin foil hat. Every one knows you just put the metal strainer on top of your head.
