Great suggestions from others , concerning getting a hands-on opinion .
Here's what I'm 'seeing' (without REALLY seeing in person) , I think -
Looks like pressed-paper frame , hand painted .
Felt backing (if indeed it's really felt) is a very odd choice for an antique oil paint item ; cardboard backing inside of frame is perhaps a 'tell' too .
Ease of removal of said felt is another red-herring .
It actually looks like a recently-produced (maybe asian) home-decor item to me .
Too many questions about it to give an informed answer from this guy .
I'm not trying to devalue your item ; (my gut is twitching on this one , which I always 'listen to')... just pointing out the opinion that we/I can't tell enough about your item , sight unseen .
