We recently received this most robust of invitations in the post. Yes, it's an actual sign made from Perspex, inviting us to an exhibition of Perspex signs by artist Mark Pawson which will open later this week on 7 November and run until 23 December at Tatty Devine on London's Brick Lane.

"I made twelve of those [invitational] signs," explains Pawson, "the colour combinations are all slightly different - a way of working which carries through to the work in the show, and Perspex/acrylic is such a great tactile material to work with – it comes in a curious, limited sort of retro colour palette. Many of the pieces for the show are ideas/designs that might otherwise have found their way onto badges or postcards but have been given a more solid tangible, 3-D presentation as Perspex signs."

Photography of these actual signs will be used in the bog-standard invites to the show. That's right, CR got special treatment: "Most of [the actual Perspex sign invites] will go to press/magazines that have covered/been supportive of my work," explains Pawson, "but if I look at them much longer I'll want to keep them all for myself!"

The signs in the exhibition have all been laser cut and etched at Tatty Devine, and all the colourful letters in relief have been glued on by hand, by Pawson. Here are a couple of signs that will feature in the show...

An Exhibition of 12 New Limited Edition Ready To Hang Signs And Some Jewellery by Mark Pawson runs from 7 November through to 23 December at Tatty Devine, 236 Brick Lane, London E2 7EB
