Shadow - David A. Sutton's groundbreaking fanzine from the 60's and 70's

I was recently going through my copies of Dave Sutton's great little literary fanzine, Shadow, looking for artwork by Jim Pitts for the forthcoming book to be published next year by Parallel Universe Publications. I wondered, perhaps, whether the early covers would be of interest to some of you, even if the first few issues had no artwork on them.
