This July 4th on Lake Norman, NC I was pulling up my anchor(45 feet deep) and on top of some gray clay on the anchor was laying the same Schlitz cap like yours....I could not believe it was as good as shape it was in.
They are brewing that beer again with the original formula,not the the beer we had in the mid 70's...which we call Sh%ts beer. The formula in the 70s was bad..Try one today, you would be surprised. It has a heavy hops flavor for a non craft beer its not too bad. It only sold in cans around here.... No bottles
