At the independent arts festival in Belgium a couple of years ago, Guido Vermeulen had a fantastic display of mailart. He had several methods of showing. Primarily he had folding screen-like frames standing along the gallery with the mailart suspended in plastic page protectors, attatched together in vertical columns. (they filled the space of where the screens would be.) This way you could also see both sides, you could walk "through" the exhibit between the columns of plastic pages. I think he probably built the wooden frames himself. It was very effective. There were a lot of pieces in his show, too many to hang. There was also a tablewith 3D pieces on them and a basket with postcards that anyone could sift through.
>>> What you saw was material from me I gave to Guido as I was absolutely sure it would be great to have his exhibition in these plastic page protectors attached to each other with a string in vertical colums. In other Mail-Art Festivals in the past I did showed Mail-Art also this way. Creating a forest in a small romm where people could walk through. Sztuka Fabryka
