7FT tall welded iron lamps ,rolled glass shade on concrete round base

on display at a paramont hotel in portland oregon years ago , unknown artist very heavy concrete form base welded iron structure with dimmer switches on both . rolled glass shade 1 is broken as shown screws in knotches to iron form . would love more info on them as there beautiful peices. dear to my heart from a great aunt who treasured them , she passed before i was old enough to ask her who could be the maker . it's a mystery I'd love to solve now. thank you Oceanpink
