Monaco: Airmail labels

Here are my first airmail labels from Monaco. Labels are the same as France's FRA-A-3d but only over stamped.

Year: 1933, Gummed. Günter Mair's catalogue no: - MCO-A-1b, imperforated, sheets of 60(4x15)
label FRA-A-3d with "MONACO-CONDAMINE" in black (stamped not printed), 5*****
