Eagle comic was founded by Marcus Morris and the first issue came out in 1950. Its heyday was from 1950 to the early 60s and its most famous character was Pilot of the Future: Dan Dare.
Rogue Planet ran from late 1955 to early 1957 and it was immediately my favourite of the Dan Dare stories. Waiting a week between issues was difficult but added to the expectation when the next issue was due. It is the second part of a trilogy: Man from Nowhere, Rogue Planet and Reign of the Robots and the trilogy is generally rated as the best of Dan Dare.
The quality of the artwork is amazing, such detail and vibrant use of colour by Frank Hampson who wrote and illustrated many of the Dan Dare stories as well as some other Eagle strips.
It is best to read the whole trilogy starting with the Man from Nowhere if you can but Rogue Planet can also be read by itself without missing anything of the central story where the planet Cryptos is invaded by the Phants from Phantos. I suspect there are some allusions to WW2 in terms of the invading forces, and their worst force the Kruels is reminiscent of the Gestapo or SS though no explicit violence above a fist fight is included in the strip. Dan and company manage to solve the situation; if only real conflicts could be solved so easily. The length of the story really rates this volume as a graphic novel, more than just a comic strip.
The quality is way beyond what I have seen of more modern comics and Dan and Co are all honest and ethical heroes.
It is great how these have endured. Dragon's Dream did a version of the trilogy in the early 80s where they commissioned Frank Hampson to draw an additional panel to replace the Eagle comic logo and make the stories less episodic. These are long since out of print but used copies are regularly available on eBay at modest prices though hard to get in really good condition. Hawk books then issued a more extensive (and generally better quality) range of all the Dan Dare stories copied from Eagle including the logo with date, price etc. The Hawk issues were very high quality and used copies are still sought after.
Sadly Hawk closed but Titan have stepped into the breech to offer the Dan Dare range. Highly recommended.
