Just cuz it's never simple...
-Are you asking about Cameroon puros - that is cigars made with all Cameroon tobacco? Can't help you there.
-Or cigars wrapped with tobacco only grown in Cameroon? (Some of the wrapper that's billed as Cameroon is grown next door in the CAR - to my knowledge, there's no difference in wrapper tobacco grown in the two countries). Can't help you there.
-A manufacturer that uses nothing but African wrapper? Can't help you there.
If none of the above apply -
AF Don Carlos or Hemingway
