Was that the controversial article that contradicted Bjorn Kellstrom's claim about starting O in the US (or something like that)? We can ask MeanGene for info (I think he was the editor at that time).
I can't tell you now because I don't have possession of them anymore as of this morning. I did keep a photocopy of part of that issue but it's not with me. I saw Gene's name as editor of a lot of those issues, so yeah, I guess you'll have to ask him.
I did see some articles about O having taken place in the US prior to 1967, including something up at Dartmouth, even, in 1949.
I scanned the NAOC 1980 and 1984 results to link to, from the NAOC Champions page.
