Note: This error should not be confused with the double impression varieties which are prevalent in the stamps of South Australia.

Three strips of four are recorded, with another in the Royal Collection. The whereabouts of two pairs in a mint block of eight in the Rosenblum (1928) and Sharples (1936) collections is unknown and hasn't been sighted since that time, most probably broken down into two strips of four and recorded above.
