Hot Air Balloon 4x Exhibition of Ephemera Advertising Postcard s

bg71 This has come from one of the most unusual collections of their kind when a postcard collector who travelled to all the British postcard and ephemera fairs tried to collect as souvenirs advertising postcards for the event that were the most unusual and collectible of their kind especially as most only had a few published for attendees or traders with stands - this is for a unique postcard collection of four postcards all using hot air balloons to advertise the events that were from up to 30 years ago - three are unused, two are limited editions (numbered on reverse) and all are mint - there are some great specialist postcards with this bundle.
