This is a Tennessee Industries Super Bird Walks on any Non-Porous Surface that in mint package from the late 1960s (my guess).   Still sealed in the package.  I am not sure if the suction cups work...since it is so old.  I am selling as is.  Stock # 515.  Please see pictures for more detail as they are part of the description.  Got a Question - please ask!! I have to the best of my ability, described and pointed out any flaws in the items I have listed.
