I thought this at first a print, the detail is so life-like and convincing, but closer examination revealed that it is indeed an original drawn work on paper, measuring 9 1/2" by 7" (15" by 13" framed). The artist must have had tremendous patience, or lots of time on his or her hands, to have created each leaf and flower. The work probably dates to the 19th century. As would be expected in art of this age, there are a few discolored areas at lower left and lower right, but they just add to the antique appeal.
