I have a large, thick and heavy vase that is a deep rich cobalt blue. It is footed, with a stepped base, and is a flattened four-lobe type shape. It stands about 10-1/2 to 11 inches tall, and is unsigned. I have also seen a much smaller version of this vase in the same color, perhaps 5 inches tall at most. I always suspected that it was a European piece; now, for the reason below, I'm sure of it.
Whilst visiting a friend in San Francisco this weekend, I saw that he had the smaller footed vase in a very unusual green color. It was signed on the underside of the foot, CARL REHM. It had a polished cutting on the outer lobes.
I see that there is a large cobalt blue goblet-style vase signed Carl Rehm on eBay at the moment. The photo of the mark is identical to the mark that appeared on my friend's green piece. But Googling the name has yielded no further information. Can anyone tell me of a book or website which tells more about this kind of glass, in the hopes that I can confirm the origin of my vase?
I don't have a photo of it just now, but can try to post one as soon as possible.
Thanks for any leads you may be kind enough to provide.
