Funky ebay find.
These are unique party-favor type things. Miniature aprons, all 41 cut from vintage fabric with pinked edges and little hand-stitched pockets...
these must have been intended for a weight-watching group of ladies. I don't know what year, but they were housed in an old cardboard box that once held metallic foil Christmas cards...
along with this type-written note:
From the Circle
This neat little apron is sent to you,
And this is what we wish you to do;
The little pocket you plainly see,
For a special purpose is meant to be.
Now measure your waist line inch by inch,
And see that the measure does not pinch;
For each small inch that you measure round,
In the pocket put two pennies sound.
The game is fair you will admit,
You waist you money--we pocket it;
And the money the pockets so freely pay,
The Circle will use in the wisest way.
