Vintage French LYS Cadre Antiparasite Tuned Frame Aerial OC PO GO Radio 1950s For Sale

Rare LYS three-band aerial with tuner, in the shape of a picture frame. Untested and sold for restoration/collecting. Please check the photos to see how complete this is - I've never seen another one like it, so can't judge.
The instructions on the back say something like

• Put the light-coloured plug into the radio's aerial socket and the dark plug into earth.
• Set the radio to the appropriate band: OC, PO or GO.
• Tune the radio normally.
• Find maximum signal strength using the "accord" control.
• If necessary, slightly change the orientation of the frame.

This is in decent vintage cosmetic condition. There is a small chip off the top left corner of the frame, and the ultra-cheap (but original?) picture in the frame is torn and mis-placed - but could presumably be replaced with something better - or repaired and re-positioned. Please see photos - cosmetic condition is otherwise good for the type of article and its age of well over 70.
