Found in a charity shop for £3, in a stout frame and with anti-glare glass!
The 737 in the foreground appears to bear the registration 9H-ABA, which is a series 2Y5 delivered to the airline in March 1983.
The 720B in the background could be any of five of the type operated until 1990, when new noise regulations in the EU forced their retirement.
Unfortunately there is no signature on the print but given the subject and the robust framing I would guess that it adorned the wall of a travel agency in the mid / late 1980s. Now it has been claimed by Percival.
