interesting photo
Obviously 1973 or 1974. Court Lines HS125 G-AVRG in front of a Gulfstream 2 that MIGHT be N1624 of Texaco although I'm not sure the colour scheme is correct (seems to end in "24"). Presumably the Aer Turas DC-4 EI-ARS nose out on stand 9 with an unidentifiable Viscount between the 2 Monarchs. I stand to be corrected of course!
