German Brewery Barware Coasters Mats Brauerei Gaag Square Green White

This stack of cardboard Germany Brewery coasters has over 50 coasters. It's a stack just shy of 4 inches high. I'm unable to identify the brewery but the first word Brauerei is Brewery in German. I think the 2nd word is Gaag, but nothing is translating for that in German. The coaster are thick cardboard or pressed paper. They are approximately 3 3/4 X 3 3/4. Perfect addition to your home bar or coaster collection. I'd guess they are vintage because of the material but I cannot date them. They have the same graphics on both sides.
