Good question! You know, you might want to send the pic to the folks at Treesje and see what they say....I personally have never seen that model in a recent Treesje, but who knows? It could be an older bag. Here's the email to use:
hi everyone! i have one treesje, a grey marley. this is my 2nd Treesje bag. I don't know what kind of bag it is, if someone can ID that would be great. It looks similar to the avalon to me, maybe it is is a special version of it? I scored this bag for $262 (that prices includes tax), it was originally $595. I love it, it might be my new favorite bag...topping all my RMs and MbyMJs, MJs, and linea pelles It looks like a brown color in this photo, it's actually a bordeoux color like grapeish.
