Södahl Egg Cups

Hello. I'm trying to date, and if possible learn the name of the pattern of the egg cups shown below. The closest I have come is a listing on the German eBay that shows a Södahl breakfast set with a flower pattern and solid color cups in brown. This set is described as "vintage" (whatever that means). According to the seller, the cups were bought in Europe and given as a gift to a late collector whose estate is being liquidated. Only the blue cup has the Södahl sticker but the shape of the white ones is identical.

I have been unable to determine when Södahl stopped offering pottery. If anyone knows, that would at least give me an "at the latest date" for these items.

Thanks for any help you can give me.

Cheers,

Earl

The good people at Södahl inform me that they stopped offering these in the 1970's.
