We need 2 or 3 pictures merged into one picture. Pictures can be looked at here: [login to view URL] 1. Picture: "[login to view URL]" to be inserted into "GS Fahrt" 2. Picture: "[login to view URL]" to be inserted into "S Fahrt" 3. Picture: "[login to view URL]" and "[login to view URL]" or "[login to view URL]" to be inserted into "CH Fahrt 2+" 4. Picture: "[login to view URL]" and "[login to view URL]" or "[login to view URL]" to be inserted into "B Fahrt 2+" Attention! If you use "[login to view URL]" then the top of the bottle must be covered - Cork is missing! The pics "idea CH Fahrt2+.jpg" and "idea S Fahrt" are ment to give you an idea how the pics should look like about.
