Mego 12 inch Spiderman. His box sports illustrations of Captain America, who was made as a 12 inch figure and Mr. Fantastic, Cap eventually was made in 1979 but Mr Fantastic never got off the drawing board.
This is the first edition (Canadian release) Spidey.
The early release Spidey had a thinner body style, the later US release Spiderman had a much bulkier torso.
One variation you may see is a Spidey stamped DC Comics on the neck. This was of course an error and was corrected by slapping "Marvel" on top and recasting. The correction is quite obvious.
The 1979 European box for 12" Mego Spidey featured some dynamic artwork and still promised a 12" Mr Fantastic.
Later 12" Spidey's came on a larger muscle body and on a very attractive card, note the free web. This card came in variation without the fly away action as well. (courtesy of Brian)

Mego 12" Magnetic Spiderman was pitched back in 1978 but wasn't produced despite being such a logical toy. There IS a prototype known to exist however...
The packaging for the Mego Web Spinning Spidey is easily one of Mego's most attractive, check out the beautiful villain clip art on the back! (Brain's collection)
