Adam20:
Do some research on this. There is an Italian artist, Alessandro Pianon who made a whole series of birds in the 1960's with stick feet and I believe that this is part of that series. I once saw one that was a cube, with added eyes and feet. I also have seen when they are properly identified, they sell for big money. Do a google image search for VISTOSI BIRDS and you will find smiliar shapes, plus a whole lot more. I have seen a bird sell for $3500 USD. Not all birds sell for that kind of money, but in a good contemporary modern glass auction with good coverage, your bird could be a money bird!
