VTG on sale Signed Strömbergshyttan Studioglas Vase Bowl, Swedish Scandinavian Art Glass, Swedish Stromberg Art Glass Bowl Vase

A beautiful and HEAVY (2 pound 7 ounces) Swedish Stömbergshyttan Studioglas bowl/vase.

It is signed on the bottom AND on sale has a clear sticker on the front. The etched signature on the bottom reads "RK.Sg Strömbergshyttan." There were 200 of this particular bowl made. I can't make out the first number - ?/200. There's also another number at the end. I'm not sure if its' a date - perhaps 1976 - or a production code. See Photos #7, #8, and #9. This glass studio closed in 1979.

The clear sticker on the front of the bowl is shown in Photo #10.

The bowl/vase is in excellent condition with no chips/cracks/repairs. I also don't see any scratches.

I'm no expert on art glass production but I think the cobalt blue decoration was "applied" and then "marvered" to be flush with the surface. This blue abstract looking decoration is only found once and is not repeated on the bowl/vase.

The inside rim of the bowl is a little "sharp" to the touch but will not cut you.

MEASUREMENTS:
3 inches high with a 3.75 inch diameter
The actual opening has a diameter of 2-5/8 inches.
