Wojciech Zamecznik’s archive comprises, apart from the printed posters, a large collection of poster and placard dummies. They are mostly large format pieces, prepared in the penultimate stage of print production. A lot of the time, they contain information for the printers, concerning the colour shades or the distances between individual elements of the design. The reverse sides have dates and times (!) of collection written on them, as well as the commissioners’ signatures. The featured gallery includes dummies for such seminal posters as the Warsaw Autumn, the Family of Man exhibition, or a painted dummy for Zamecznik’s very first poster Uprzątnij śmiecie (Pick Up Your Trash). All dummies are shown in the pre-conservation state.
