Do Not Fold - - - - - - - or Mutilate

"S-P-I-N-D-L-E "

What does that mean?  

I have a feeling that there's a 

generation or two who have no idea.

 Decades ago bills, receipts and other important

papers were organized by being stuck onto a spindle.

Many were free standing - this one hung on a wall.

Early computers relied on punched cards with 

a series of uniform holes for input & output of data.

A raggedy, misplaced hole would 

muck up the whole operation.

IBM began printing the phrase 

"Do not fold spindle or mutilate"

on the cards.  

And that's the origin of the phrase.

Have a lovely weekend!
