YOU may not know their names ­- but their work is known to millions worldwide.

The work of teacher and student Tony Forster and Phill Grimshaw, who met at the old Bolton School of the Arts, is behind many well-known designs and logos.

Now an exhibition showcasing their work, Men in Letters, will go on display in Bolton next month.

It is the brainchild of lettering artist Dan Forster, whose late father Tony was the man who designed the logo for rock band 10cc and Paperchase, the international chain of stationery stores.

Dan has teamed up with graphic design lecturer Anthony Roocroft and the University of Bolton’s School of the Arts to present what is possibly the most extensive exhibition of hand lettering and calligraphy ever displayed in the UK.

It will run from February 8 to March 8 at Bolton Museum and Art Gallery in Le Mans Crescent.

The works are those of Dan’s father Tony (1941-2008) and Tony’s former student and close friend Phill Grimshaw (1950-1998).

Tony was a prominent figure in the design scene between the early 1960s and his death in 2008 and taught regularly at Bolton School of the Arts.

As well as lettering work on the iconic logos for Paperchase and 10cc, he designed the BBC Philharmonic Orchestra logo.

He won more than 25 international design awards during his career.

Phill Grimshaw went on to become an internationally-renowned typeface designer.

Most of the work displayed has remained largely unseen, as it was not produced digitally.

The exhibition reveals their sketches, mock-ups, final artwork, original calligraphy pieces, typeface designs and original posters, all produced by hand.

Dan said: “The exhibition has been a long time in the making. Following my dad’s death, I set to clearing out and organising his studio, a process which spanned eight years.

“I knew from day one that something had to be done to share my dad’s incredible work. Now through this exhibition we hope to highlight this hand-rendered work. I’m sure it will be particularly interesting for a younger generation of digital designers.”
