*DC: An often-overlooked first appearance is Adventure Comics #269, from February 1960, in which Superboy and Krypto faced the menace of “Krypto’s Mean Master!”, but – even though you can’t go far wrong with a crying super-dog on the cover – it was the back-up Aquaman story which featured the breakout character. Aqualad (Misnamed Aqua-Boy on the cover), an orphan from Atlantis, became an almost constant presence in Aquaman’s own series, and a founding member of the Teen Titans. With Aqualad’s 50th Anniversary coming up, this VG/FN pence copy is on sale at £60 and a relatively affordable opportunity to pick up a premier appearance.
