showing an `ARPA` medal, plus a few additional information. As the english text is a bit faint, here`s a copy:
Circular bronze medal with loop for ribbon suspension; the face with the head of King Carol II facing right, circumscribed 'M. S. REGELE CAROL II. AL ROMÂNIEI' (H. M. King Carol II of Romania), signed 'R.FÖSSLER'; the reverse with the letters ARPA (for the Asociatia Româna pentru Propaganda Aviatiei) and the dates '1927-1933' above and below a stylised wing, circumscribed 'ȘASE ANI DE MUNCA PENTRU FLOTA NAȚIONALĂ AERIANĂ' (Six years of work for the National Air Fleet); on original ribbon in the national colours of Romania. The Association was founded in Bucharest in 1927 with the aim of popularising flying. It acquired more than 40 aeroplanes and was active at the Baneasa, Clinceni Giulesti, Otopeni and Popesti-Leordeni airfields around Bucharest and elsewhere in provincial centres such as Alexandria, Cluj and Iasi.
