Yes, Vasart (until such time as we get any good info that Salvador Ysart made bottles in that style pre-war). I have already given the seller the basic info about that one (which I believe is a relist from a prior listing a whle ago) and the one that they sold very recently. I said they were not by Paul Ysart.
I have also suggested that, for info on Ysart-looking items they might consider dropping in to the GMB as well as looking at my web page on bottles of that style to check out features that indicate Ysart work and that of later, as yet unknown maker, items.
