This is a follow-on to a question that I asked a few weeks ago.

TTT tried to help me but it seems that we were going in the wrong direction.

Using my new spectacles and a magnifying glass I have managed to locate a little more information from the leaflet.
"modèle déposé - Breveté s.g.d.g." is printed at the bottom of the middle page of the leaflet.
I have discovered that: Breveté SGDG was a French type of patent that ceased to exist in 1968. The name was a common abbreviation for "Breveté Sans Garantie Du Gouvernement“
The 'picture' in the middle of the leaflet is constructed by a few layers of plastic with trees etc between the layers.
Can anyone tell me if this item has another name? Uncle Google gives me many results but none of them is in any way similar to this item.
I am off to bed to play with my Kindle - I will be back.
