Four of these Camel cigarette advertising cards are available.  We think they say “never throw a burning camel out the window,” or the Greek equivalent.  Two of the cards are unused (Grades: 1, $5 each).  Two were mailed: one from Malaysia with an uncancelled stamp in 1997, and one from Hong Kong in 2000 with full postmark. Those two have some postmark smudging on the front (Grades: 2, $3 each).
