Dear Frere Diego, I’m Peter Ernst and a member of the group ’Hollandais’ who visit the carrières the Confrecourt last april. During that visit we met briefly. At Confrecourt I took some pictures. Your group is also present there. If you want them, you can send me a mail and at your request I will send them to you. Sincerely yours, Peter Ernst, Gouda, Pays Bas
