Very art deco inspired these!! & highly collectable & decorative!! Sorry I have not idea what kind of brand they are!! But they are very appealing !! & ready to be used as lamps or any other use !! Maybe mounted inside something to make it look posh!! Diagonally designed!! & ideal maybe for outdoors luxurious lighting display ?
