Anyone recognize these Danish chairs?  

Hi all, I just realized that I had not uploaded the photo of the entire chair. I hope this will help... any guesses, ideas, leads would be very much appreciated!

Found them. They are Erik Buck (Erik Buch).
This seller has them, and they are marked: Chr. Christensens MobelFabrik I/S Vamdrup Design: Erik Buck

I found this chair the other day with [some] similar attributes.
it's walnut with vinyl upholstery.
Any idea what it is?

Sorry, no idea! It looks American, though.

I'd have to agree.
Just thought it was funny, similar shapes.
Your chair is lovely..
