Handblown Czechoslovakian drinking vessel

This is one of my favorite glasses to Finish off a bucket of beer with! 10 5/8" inches H x 2 5/8" W at the rim. Picked it up for about $2.75! I couldn't get the money out of my pocket fast enough. Hand blown! Mind blown!! The skill level on this pretty dang high! It is etched with the signature from artist and has a sticker stating it's Czechoslovakian origin. I think their Boar Heads or possibly Bear Heads! And if you notice in the picture with the liquid those heads are incorporated into containing The livation or drink of choice. My Best guess would be The artist re-creating respectfully and skillfully an traditional older forrest glass style and color!
