Hello. From time to time I see such beersteins – yellow and with red stripes. And everyone is trying to understand who is the manufacturer? Which country is Germany or Austria from? Maybe someone has some information on these steins?
I tried searching the image of the mark on the bottom of your stein, but I did not have any luck in matching it. It does look similar to a mark found on Dorfner & Co. steins, see https://www.steinmarks.co.uk/pages/pv.asp?p=stein367. They did make creamware steins.
