I've uploaded a new image for this file. The previous image claimed to be the cover of the 1975 edition of the book. However, the publisher logo on the cover appeared to be a newer one than the one used in 1975. The cover image I've replaced it with shows the original 1975 cover price of $1.50 and has the correct DAW collector number (140).--Rtrace (talk) 03:53, 5 September 2008 (UTC)
