It looks like the Penguin India reprinting of the entire 'Garth' series (for which Peter O'Donnell wrote from 1953-1966) is being delayed. The original news release on the Penguin India site, in 2008, said:
"The third major reissue in our retro revival series will be the Complete Garth in a collectible 5-volume hardback graphic novel box set. Garth is a character well known to most Indians through newspaper strips and a brief run as comic books from Indrajal comics. Though there have been a couple of annuals and two dedicated volumes, never before has Garth ever been collected. So for the first time ever fans can get all 16,000 strips covering 165 stories in 3,000-plus pages."
However, the micro-website for the Retro Revival series (which recently reprinted the entire Modesty Blaise series, as well as all the Madeleine Brent novels) seems to be down right now, so looks like we have to wait for more news...

So far the artwork for the Retro Revival series has been stunning, so hopefully we can expect the Garth reprints to be just as good!
