This I found at an Estate sale in Las Vegas, Nevada. There are two rocks glued at the bottom. I think there used to be three. I am not quite sure of the significance of them, or of there is any at all. The light blinks and then stays solid and then blinks again as if it is on a pattern. (Not quite sure)This may have been a homemade E.T. It is dated "83" on the bottom. Also there is an "H" next to the date. This is very cool and I cannot find another one like this anywhere, which leads me to believe it was a custom made E.T. Enjoy!
