That is interesting! A double sided purse. perhaps one side meant for coins and the other for notes? I'm wondering if it is a change purse that originally came inside a matching larger bag.
Yes it would help to know the size.
It looks like it's fabric and the rose is painted on in some way, rather than embroidered?
And what is the lining fabric, can you describe it?
I'm thinking 50s/60s maybe.
