I had seen the auction listing before I read the message in here, but I was not inclined to make any comments, as I usually do not do so for current listings, unless I see a major error in something that I have particlular knowledge about (which is actually not very much at all).
I am in favour of sellers adding researched information to eBay listings, and well done for making the effort, Rachel. But in this instance I wonder whether your summary is accurate.
The information about the "small scratch" that Vicent Ysart made in the Babycham glasses was, as I understand it, given to Angela Bowey (our host for this Message Board) by Colin Terris and appears in Angela's article in her Glass Museum site (as located through the search info given by Rachel). However, nowhere does it say anything (that I can see) to suggest the wording you have added to your listing:
... or as in this case a circular etching combined with the word Babycham.
In fact, the only additional text I can find in Angela's article relating to this is the wording
... with the rough patch scratched in the bottom
, which seems to confirm that it only that ... a rough scratching.
Unfortunately I don't know much at all about the Babycham glasses, but it certainly would be useful to know whether there is any reliable information about who actually applied the etched Babycham name, and when this was first done. I suspect it was not at the Vasart works, but I could be wrong.
Any ideas Frank, or anyone else?
