Thanks for reminder about the pontil vs pontil mark--I knew this, of course, but there I was getting sloppy about the terminology. I get the same reaction when folks use the terms etching and engraving interchangeably, so I appreciate how irritating it can be!
I am not thinking that the vase is older than the engraving. The vase would have been made for an engraving, otherwise the large oval would have looked quite strange with nothing on it. And these old shapes continued to be made, even up to today, as you mentioned, Sue. I have other wonderful (fortunately marked) examples of 1960s/1970s Central European glass that use glass designs from prior to the mid-1930s. I wouldn't think that having a post WWII design on a pre-WWII shape would be that unusual, which is why I initially thought that it was from that area. But I have seen traditional shapes being used today by Scandanavian companies, too (although not this particular shape), so I still can't be sure whether this vase is Scandanavian or Central European (and may never know!).
