Outstanding 1930's 3D Holographic Advertising Picture.

This is a bit special and a very very rare find.
A 1930's / 40's advertising picture.
3D holgram image of a lady advertising'Waved by Superma Machineless'.
The advert was for a perm for ladies.
The image though follows you round a room.
From wherever you stand and look at her, she gazing straight back at you.
Incredible image; never seen anything like it.
Mounted in a decorative gold gilt frame.
Approx. Max. Dims: Frame: H: 645mm W: 570mm, D: 90mm.
In excellent antique condition, nothing to report other than very very slight loss to the left edge of the frame as you look at it, barely noticeable.
This is an original antique and may well show signs of use and wear commensurate with age.
Please do study the photos and video as these form part of the description.
