Purgatory Pie Press and the artist Elizabeth Duffy have collaborated on a book that utilizes as source material everyday ephemeral patterns, specifically the interior security patterns of envelopes and the visual language of analog mail. The result is a page-turner of overlapping patterns and forms. Purgatory and Duffy culled patterns from their junk mail to create this paean to the quotidian.Enclosure Exposure is letterpress, diecut, and printed collagraph, and handset type in blue and black, signed and numbered in an edition of 200 by the artist together with Dikko Faust and Esther K. Smith of Purgatory Pie.
