Is the stretcher?

[Дженни]

Question connoisseurs.
Acquired by now 1971. oil on canvas, 60 cm * 80 cm I wanted to make the frame, but bagetchik said that the sub-frame of the curve, you need to change. Change or leave as is? I would like to frame as going to put a picture on the wall to the house. Site about the restoration revered. It seems to be like and not afraid to replace the sub-frame - the main thing that the specialist was good. And then suddenly, the picture will lose something very important? Advise how to proceed, please!: Confused:
