Hi: It's not a Gallery piece, but a production piece. In the Orrefors catalogue for 1940, according Ricke, Swedish Glass Factories. I'm not a huge fan of engraved glass, but these pre-1950's pieces from Orrefors are stunning. There's a series of vases with similar motifs designed by Lindstrand, Landberg, and Ohstrom.
These pieces seem to fetch a decent price as the last similar piece that was on here, what appeared to be an unsigned Lindstrand piece, went for over $220 on eBay.
