In this feature, I spotlight comic book covers that follow a specific theme. Here is an archive of all the cover themes we've spotlighted so far.
With their books cover-dated October 2009 (so roughly August 2009), Marvel decided to celebrate their 70th Anniversary as a company (unlike their 1986 25th anniversary, which only celebrated the beginning of the Marvel Universe specifically) with a series of variant covers in the style of their 25th Anniversary covers from 1986. Jim Cheung did the border art and a variety of artists did the spotlight art. So today, here are all of the Marvel 70th Anniversary covers (Thor did not come out that month, so as far as I can tell, it did not get a 70th Anniversary cover).
