Beautiful cased glass, cut to clear snuff bottle. It is hand-blown, with polished pontil, lipped neck, and carved blue designs on the sides. The reverse painting on the inside is exceptional. The bottle has a foot cased in blue on the bottom. The top is yellow glass with the ivory dip spoon. The bottle measures 2/4 inches tall by 1-3/4 inches wide. We are not experts on snuff bottles, but this one looks really well done. Age unknown. The bottle is in excellent condition except the cork under the lid is partially deteriorated. The bottom shows wear. There are no marks.
