We called them sperm letters, even though they were made of glue. For the poster LysistrataI had taken pictures of my cat Duivel in a golden cage. In Lysistrata, the women of Athens rebel: they’re not going to fuck until there is peace. Ruben Steeman made the letters for the poster. Of glue, in this case. Later we decided to make a complete alphabet of it, but then made of glass. That turned out to be more difficult than with glue.
