President George Vella opened the 20th philatelic exhibition organised by the Gozo Philatelic Society at the Gozo Ministry. Dr Vella extended his stay at the exhibition to well over an hour since he inspected all the exhibits, uttering words of praise and encouragement. GPS secretary Antoine Vassallo gave an album to Dr Vella. The album, containing Gozo-themed covers, was designed by Anthony Grech. The exhibition remains open until Tuesday.
