Please don't hate me for just posting a quote here, but I like it and do not want to forget this one...
Basically I don't call this work made with colors watercolors or whatever. First of all I call everything drawings. Whatever oil paint or mordant. I despise chalk, but charcoal I tend to like more, or graphite. Chalk doesn't suit me. So basically everything is drawings.
Joseph Beuys, 1970
(From "Joseph Beuys, Early Watercolors", Schirmer's Visual Library, page 7.)
I really like how this little snippet out of a conversation or a talk has been blown up into this "quote", and how the translation makes this thing even more bizzare...
