The most desirable wall of frames in Paris

To prepare for the end-of-year celebrations, Esther & Paul took all their works out of their sack, put them on the floor, and scratched their moustaches. What should they choose to create the most desirable wall of frames in all of Paris? Which works will please on December 24th and allow all budgets to offer a unique piece? We put down our hats, rolled up our sleeves and bang: a few vintage works here, two or three watercolors here, a still life, a bit of gold leaf and that's it. The hardest part remains: choosing!
