Ooh, a pattern to copy

 
I am so pissed at myself for not watching this ebay auction, and letting this vintage apron get snatched up under my nose. Why didn't I bid higher? Grrrr...
What an awesome bird-on-a-branch pattern. I wonder if it's a one-of-a-kind, or a commercial pattern? Do you think it's bias tape with embroidered details? Anyway, I'm posting it here to inspire myself to make my own version, and inspire you to do the same.
