I was away to France for a week with our regional prehistoric society, called DPV. Off the beaten track: dolmen, cave paintings, digs.
For the 2 board members who had arranged the trip (and did a lot of work during our activities) I made a small present beforehand: digitised the logo and embroidered it on guest towels.I apologised that I did not know whether the copyright was owned by the designer or by the society - and none of them knew. The one who had arranged it years ago had long since died.
The logo is used on their quarterly magazine and on every letter and announcement made. But nobody had ever thought of using it for embroidery.
Anyway, more research needed.
Here's a computer image (forgot to take a photo). The (rather clever and simple) logo shows the D and P and the lines suggest the quadrants that are so typical for archaeological digs.
I left school in 1956 and had not spoken French since then. Could still read it and write it to a certain extend. But understanding the spoken language was rusty to say the least. And I certainly never learned the technical archaeological lingo at school. I could converse with the waiters and hotel receptionists, but fancy 2 lectures and a number of museum guided tours all in French - I was exhausted every evening!!
