Unmotionless Mollie (1920 snapshot)

There's a cursive inscription on the back of this tiny photograph. It states:

12-5-20
Me in office
I moved
1 mint minute
was too long
to sit
motionless!
Mollie

The photo is only 2¾ inches wide, including the black border. So the image is very small. That's too bad, because with a bigger photograph there might have been more interesting details to discern among the items behind can't-sit-still Mollie.
