Publication Dates[]
I had all of these long ago. I recently reacquired the swimsuit one via ebay, and added my scans and notes to what 23skidoo did. I have no idea if the 1977 date is accurate, since I don't have these. Can anyone verify the dates for the silo and SCUBA books?--Major Sloan 04:58, 10 June 2009 (UTC)
