South Africa was slow to introduce an air mail service to speed up the delivery of local mail. Eventually, in 1925, the Civil Air Board in South Africa decided to institute a three monthly Experimental Air Service between Cape Town and Durban, to establish whether such a service could be provided economically and reliably.
A set of four Air Mail stamps was specially printed specifically for the Experimental Air Service that was inaugurated on 2 March 1925. The 9d was the highest denomination in the set. These stamps were only valid for the carriage of mail on the foregoing service.
