*Marvel: In common with many long-running series, the Avengers has seen the premieres of a number of guest heroes or villains who went on to greater things, and four such issues are added this week: in Avengers #28, Cap’s Kooky Quartet (plus Hank & Jan) faced the might of the Collector, later seen in the ‘Guardians of the Galaxy’ movie series; in the silly but superb issue #83, we met the Valkyrie for the first time, plus the Lady Liberators; #144 brought us the debut of Patsy Walker Baxter’s superheroic identity, the Hellcat and #257 introduced the alien warlord (warlady?) Nebula, later incarnated on the silver screen by Karen Gillan. All four are shown here:- #28 VG/FN p £45, #83 FN p £65, #144 FN+ £25, and #257 VF p £25. SORRY, THESE HAVE NOW SOLD
