The colour of this drawing is paler than in the majority of the photos. The inscription appears to read "For Eddy with Love".

A typed note on the back indicated the provenance as Gimpel Fils - November 1964. I followed it up and showed the work to Gimpel Fils who were confidant of its authenticity and kindly obtained Mathieu's own confirmation. I will provide either a note from Mathieu himself or (given his age and some infirmity) a letter from Gimpels Fils proving authenticity.
