Pre-prohibition brass beer bottle opener advertising for Luxus the beer you like this is from the Fred Krug brewing company, Omaha, Nebraska please note this does have some where to this opener. I will show several photos.

Prest-o-lite key is what the square opening is called and it was used to turn on the valve on automobile gas headlights from about 1910 to early 1930s before electric headlights were widely used hard to believe something advertising beer could be used on your automobile.
