Janus Stark in colour

Just come across this, and what an unusual treat it is - a nice self contained story in full colour.
Normally, that'd be a ghastly notion, not suiting the Victorian setting or the character at all, but it works here in that Janus is far removed from the sooty streets of London and is instead employed to brave the traps of an Eygptian Pyramid to retrieve a piece of treasure, predating Raiders Of The Lost Ark by a good 6 years. The thing that doesn't work is the strange decision to colour in some of the speech bubbles too, which is horrible and really detracts from the art.
Speaking of art, i'm unsure who actually did it. The above splash page screams Ian Kennedy, but the close-up has me doubting. But the figure directly below looks like classic Kennedy. So i'm going with him.

Whoever it was, also did the Raven Of The Wing exactly the same.

I'm guessing both were done in colour as they were for the 1973 Valiant annual, a much more colourful title than its weekly brother.

Also in this copy is the resolution to a Kelly's Eye story i've featured here before, where he's up against the dread vampire, Count Varga. Except he's not. In true Scooby Doo style, he's revealed to be the lowly manservant all along and the terrifying giant bats turn out to be helicopter-like craft. Operated by midgets. Brilliant stuff with brilliant art by Lopez.
