Loetz Cameos: Sailboats and marks

I decided to photograph Cameo Landscape vases that show sailboats. They were all made by Loetz for Jouve, but exhibit different marks.
Top Yellow/Brown: signed with the oval mark--the only one I have found.
Top Green White and bottom and bottom Green/Brown immediately below both have the familiar Richard mark.
My newest arrival in blue/purple with a rare Fisher mark.
