This piece is what is called a whimsey piece, Very skilled glassmakers of the carnival era produced these odd fancies at many factories that weren't part of regular production, sometimes on the sly to sneak home to give to a loved one, some whimsey shapes gained such popularity they were soon put into production, other pieces bordered on the grotesque in their shaping and still seem strange to us today, these pieces are one of a kind!!! Very nice piece
