A possiblity in view of the colour perhaps - and the wear.
Just as a matter of interest - If you scroll towards the bottom of Steven's link, the bowl is shown with a lid (with nude figure), possibly a cream container - and then a little further down on the same side it appears again as a stand alone bowl.
When looking through the Truitt's book previously, I'd assumed that the name 'Ingrid' applied solely to the malachite sort of lapis and jade coloured pieces, which I think is the only Schlevogt material in their book. Now I'm not so sure that assumption is correct, as there are other pieces in Steven's link in clear and frosted glass (like this carp bowl) which certainly aren't in green glass. Perhaps someone can comment please.
The Truitt's do comment in their book that Schlevogt had been very impressed by the quality of Lalique's pressed glass, and apparently he was determined to try and reproduce this in his 'Ingrid' series. After removal from the moulds, pieces were further worked in an attempt to 'accentuate the relief and remove all traces of the seams'. Obviously, they didn't get around to my bowl
Isn't that bathroom and fireplace, in jade green, mind blowing - sadly probably now doesn't exist.
