This just in from Are Myklebust:
[A couple of comments to postings on your blog lately:
1) Interviews with Paul Murry;
There is one more that exists: Klaus Spillman: The Man Who Drew More Tales for the Mouse: An Interview with Paul Murry. The Duckburg Times, no. 16, pp. 17-23. Private press (Frank Gabbard), 1982. Check this link.
2) Mickey Mouse Sunday pages:
In fact an Italian book from 1977 exists that reprints most of this early Sunday pages (also published in other Europeans countries).]
The worst thing is that I have both a copy of the Spillman interview and of the Italian book (translated in French) in my archives. This is what 25 years of collecting will do not you.
