So I figured that eventually, I would have to have one of my old frames cut down to fit (which costs about $100). Then yesterday, I was in the city looking through some antique shops when I came across this antique gold frame above. To my utter shock and pure joy, they were a match!
Both frame and painting are very happy to have found each other - I think it was absolute destiny! xo
Details on where I hung it will come later!
