Cool article, but perhaps this should be located at windowed envelope since there is little information on Callahan himself. Guy Fuchsia 20:58, 10 May 2007 (UTC)[reply]
I actually had a similar thought after writing it up -- it's been difficult to find a verifiable source that I can use for info on him, specifically, other than what I have from first-hand accounts of his friends and family. I tried scouring Google but came up empty-handed. Might anyone else have any better luck at tracking down some info? --Bossi (talk ;; contribs) 22:40, 10 May 2007 (UTC)[reply]
