Even though it is the Doc Doom cross-over, I always thought the cover was rather clunky...and the first Spider-Man that didn't introduce a new villian (recognizing that #1 had an FF cameo as well)...for me it is the weakest of the covers/issues 1-10...1 is weak too, and perhaps some would list #7 as being the 2nd Vulture, but 5 will always be the weakest to me...
BLASPHEMY I TELLS YA!!!!!
This cover is one of my favorites for this very reason - Spidey looks like such a dork, w/ Doom cutting his web-line.
Let's face it - Ditko had a style all his own and those quirky characters drawn with the pie in the face expressions are part of the appeal.
Compared to today's artists, they look very amatuer, but in my mind they are timeless.
