Any idea of chair designer  

American, walnut, circa 1953, Edmund Spence, Urban-Aire chairs.

Thank you!!

Dearest Leif,

You have one big brain. I am forever impressed with your knowledge, and I am thankful.

Best,

Your Aunt Mark

Thanks Aunt Mark

Not that i know anything about the subject. But out of curiosity, I looked for the name to see what else was out there by this designer. And since i reckon there is a thirst here for accuracy, i thought, Leif, this might interest you:

The name appears to be Edmond ( with an O) J Spence. And there is a one R. Spence trying to make that point on Pinterest.
