You have an antique early 20th century color lithograph advertising poster for Metz Beer that was published by Brown & Bigelow. These were given as premiums for wall decor from the vendor to businesses who sold Metz beer. On today's market, your 2'+ color lithograph Metz Beer advertising sign, with some condition issues and out of frame, depciting a lively scene of a group in a German Alpine tavern setting could sell for as high as $150 - $300 on today's auction market. If it were in fine condition and in original wood frame, it could sell for $400 - $600.
