I haven't been reading along with you, but I watch for what you read and sometimes read some of the books during the week. However, this book is part of my favorite series of series.
The cover story was reprinted as the opener of CLASSICS ILLUSTRATED 138A SPECIAL ISSUE. Some other issues had this experience as well since both titles were published by Gilberton Co. I never saw an issue din school, which was the distribution site, but have been quite happy to download all that have been posted here.
I realize copyrights on CI and CI products are claimed by Jakk Lakke (sp) in Canada, but I question that. However, I believe he only acquired those that were published by companies contracting reprint rights for given periods of time, so these books should be fine. I also believe CI and others that haven't been reprinted since 1969 or so should be PD. Those reprinted by Jack Lake Productions and Papercutz would be more questionable. Approximately 30-35 titles were replaced using new art before 1965, so the originals of those issues should be PD. Eleven of those have 64 interior pages, 10 have 56 and the rest have 48. If Mark needs more info, we cn arrange to contact off-line. Paw Boone should have my e-mail addy.
