Nice old sterling Beer 1960's pocket protector. This is a great find you just won't see everyday. For those who don't know: a pocket protector was an item worn mainly by men. It was placed in a front shirt pocket or a jacket pocket to store pens/pencils. This protected your clothing from getting ink stains. This particular one by Sterling Beer has a cool slogan from the early 1960's when they came out with the wide mouth bottle/can. "Give A Big Mouth To Someone You Love."
