Taking place at the Novotel in Hammersmith, west London, 100-plus British and international pen dealers will be gathering.
This is one of the largest such events in Europe and thousands of vintage pens are for sale alongside new models, and penmakers and pen repairers take stalls.
Mark Gatley of Vintage Fountain Pens is a regular at this show and specialises in vintage Parker, Conway Stewart and Sheaffer.
Currently for sale on the website is a black celluloid Parker Duofold Premiere pen priced at £225.
Made in Canada, this was one of the so-called ‘Thrift’ pens produced during the Great Depression in the 1930s.
