I Have This "Marvel" Comics Poster,There Can't Be That Many Legit Heroes Is Ther

I have this exact poster on my wall.
I thought I'd mention this to see if you guys can maybe tell me if there is actually that many Marvel characters or a bunch of fakes.The obvious ones I see,the others are harder to see.I've included the biggest picture I could find.Surely all those background heroes aren't real,it looks as if there's hundreds.What do you think?

Well the anwser to title of your thread would be no there not all heroes I can make out both Doctor Von Dom and Mystique in the picture and there both villians. As far as whether or not Marvel has enough characters to fill up that poster I would say yes especaily if they included characters that are either dead or no longer used in any series.
