I found the other one, it is Todor Angelov (https://www.openstreetmap.org/node/8377921305)

About this one, shouldn’t we split the artwork into two POI?  The way I understand it is there is a bronze bust on top for Raymond Foucard, and on the structure itself a plaque for Roland Foucart.  Two different people, two materials, to artists.

It is very hard to see on Mapillary: Angelov is the one in front, and Foucart can be seen in the back, hidden behind one of of the large stones.
