Essential Thor Vol. 4 review. Classic Game Room presents a CGR Comics review of ESSENTIAL THOR VOL. 4 from Marvel, released in 2009 and collecting THOR #167-195, from 1962 to 1972, and featuring the legendary talents of Stan Lee and Jack Kirby. Part of Marvel's Essential line, this monstrous behemoth of a book collects 19 black and white issues of Thor. The novelty aspect runs thin fairly quickly, though, and only big fans of classic comics and Thor should check this one out. CGR Comics Essential Thor Vol. 4 review features footage of Asgard being constantly under attack, as well as some of the great characters of the Marvel Universe. And lots of medieval speech.
