In the context of my work for The Israel Museum's "Recycling" exhibition. I collected all the waste material from the Museum on 22.5.75. Although this material is NO longer usable, it retains the traces of the various activities carried out on that day. This waste material will be placed in plastic containers, put into a pit on the Museum's grounds and kept there. The waste matter will, therefore, in the future become documentary material. I am sending you, in a plastic bag, an original sample of this waste material. Please return the bag with your suggestions for recycling it. Mail to: Recycling Exhibition, Israel Museum, Jerusalem 91000, Israel. Your reply and bag will be included in the exhibition, which will open on June 5th, 1975 and last for two months. Thanking you in advance. — Dov Or-Ner
