Well its a 1970s or 80s Michelob bottle that has been reheated and formed into a vase or something similar.
If there is any value in it (and I am doubtful) it would be the person who created this is famous (as in Andy Warhol type fame) but you will need to find out who that person is based on the engraved signature. Keep on searching, I hope you prove me wrong on its value!
