I purchased this and a handful of other antique works on paper listed today from a friend and longtime paper dealer in PA, who has been the source of numerous treasures. Just a lovely old watercolor, theorem style with its sharp outlines, and I really love the combination of the mottled (marbled?) pink and white vase together with the base its sits of, with finely painted spidery dark blue lines evincing marble indeed. Plus morning glories, feeling always like metaphors, one here rising as if to meet the sun, the other drooping as if afternoon has arrived. 

6 1/2" X 4 3/8". Good antique condition, mid-third quarter 19th c. I would guess. Watercolor on wove.A little roughness along top edge and remnants from a table along to top edge on reverse.
