Only 13 Muscles Are Used To Smile!

I shared this "Frown - Smile" mini-poster with you a month or so ago, but today seemed like a good day to post it again. 

Every time I walk past this 1960's "Vari-Vue" motion image card in my bedroom, I can't help but smile.

I'll need to keep my eyes open for more of these vintage Vari-Vues. They're definitely day brighteners.
