I've been reading Groo for 40 years, and I'm now going back for a re-read of some of the early issues. This collection includes issue #s 9 though 12 of the Marvel comics run for the blundering barbarian, and these are some classics.
The art is pure cartooning genius by the legend Sergio Aragones. Yes, it's goofy and very much of a pure "cartoon" nature, but there's a deceptive mastery behind it all. The immense detail is obvious. What's less obvious is Aragones's skill with perspective and his ability to build entire, textured worlds on a comic book page. The closer you look at his many, many detailed panels and pages, the more little sight gags you'll notice. The man was just a bottomless well of humorous imagery. These particular issues of Groo are in the earliest years when he had fully locked into the style he would use to tell Groo's stories.
The stories themselves are also great. Co-writer/script writer Mark Evanier (Aragones often came up with the story outlines) is in fine form with these ones: Issues #9 is a fun parable involving two towns where pigs and apples are sacred, setting up hijinks for Groo and The Sage. Numbers 10 and 11 introduce the first stories with Groo series mainstay, Arcadio the Hero, whose immense good looks and reputation are outdone only by his vanity and need to adhere to classically chivalrous (and empty) displays of honor. They're great, almost Quixote-esque send-ups of medieval romance tales. Issues #12 features Groo becoming part of an acting troupe, which goes pretty much how you would expect if you know anything about the brainless wanderer.
If you come across this collection and have never read Groo, it's a great introduction to the series. If you've read a few Groo stories, enjoyed them, and are looking for more, this one will give you just that.
love Groo and recently had to hunt down all the trades as I can't see it being collected in my lifetime, we need complete groo in omnibus or library edition or even compendium.
