Fun German Beer Stein

This is a German beer stein measuring 5" x 4" give or take, and 6" by 5.5" with the handle and lid handle. The front says Gur-Holz with a banner that says Fallen alle Neun kannst Du "Hurra" Schrein. The lid says ein and zin, both of which I think are only partial words. The bottom has an M underlined with an R underneath in a symbol that I cannot name. It looks like some kind of bowling stein. It also appears to have a 7 on the bottom. I thought it looked fun, so I bought it. I know nothing about steins.
