I've just had an email from Claire Beynon, regarding copyright. Her publisher, Roger Steele of Steele Roberts Ltd says the copyright remains with Claire. He suggests we should use the following in our colophon:
Paper Wrestling by Claire Beynon, published by Steele Roberts Ltd in Open Book - Poetry & Images (2007)
I hope this means anyone still wondering, and hesitating, can happily go on with (or commence) interpreting Claire's poem.
