The poster of Tracing Board Treasury is part of a poster series for the building’s Bulletin Board: forming the announcements introducing each section of The Palace of Typographic Masonry. This poster resembles the walls of the Tracing Board Treasury which are constructed from triangular bricks, depicting the symbols of Freemasonry. Like other announcements, the poster is silkscreen printed in a set of three colours – green, silver and red – which through overlap and transparency produces a vast array of mixed colours.
