Well, Doug as I see it..... (IMHO) "It sucks to be your friend".
Five things going against them out of the blocks: (again IMHO)
- "The Kiss"
- LJ
- TC
- Superior
- Price
"The Kiss" is no small poster. . . so with that you are already at $225 with mat and museum glass.... better to go print transfer and framed to the image.
So now you have $400 to spend on the frame.... This leaves you with a limited assortment of TC or Superior.
Wants it to be Art Nouveau . . .
OK, moving on to their Georgia O'Keefe knock off of Keen during his Dali Blue period......
OK, a little more levity...
"The Kiss" is a romantic with Moorish over tones. The seemingly random pattern of geometric pave' sets the tone of pattern. (yes, the couple is incidental). The frame would have been a flat panel with subtle welting. Any incising would be very shallow and possibly a Moorish or Gothic cartouch treatment in the corners transitioning into the plain field between the welts.
If there is any other pattern or adornment, it would be very shadowy sgraffito or just line markings in the gesso that would ghost through the gold. The patterns would be burnished or not for a color-on-color look but an overall homogeneous gold panel about 3-4" wide.
Any toning should be with burnishing and abrading until the rouge starts to hint through the metal.
A tiny bit of gauche (deep verde and a touch of burnt umber in a very thinned out wash of shellac maybe. This will deepen the shadows, and temper the "spot-lightness" of the gold.
About $3,800 should cover it.
