Another Pair of Puce and Green. Rosenbaum's Bitters

Here is a pair of early western squares in shades of puce and green. The "large" size Rosenbaum's Bitters, N.B. Jacobs & Co. San Francisco. This size is listed as R-93 in Ring/Ham and is considered rare. I believe there are about 30 of this variant of the Rosenbaum's in collections although I am not certain of their condition. These two are is a light yellow olive green, and a cherry puce with pink tone which did not photograph very well today. It is believed that this version of the large Rosenbaum's may have been blown in the East, and the examples with the tapered collar with ring were blown in S.F. The base characteristics are also different with one having a dot in the center and the other not. I believe these are mid 1860's bitters and come in many colors from amber, to olive amber, light yellow olive, to more green, and occasionally puce and even a pastel blue green as well as a true wine or claret. I would be interested in dividing them up as to color "rarity" similar to the Lacour's. These are historically significant and early western bitters. DM
