I picked up IDW's Definitive Flash Gordon and Jungle Jim Volume 1 last week with a bit of hesitation has I already had Checker's and Titan's first Flash Gordon volumes, but the full Sunday pages size (actually slightly larger) and colors( that are a good compromise between Checker's glossy ones and Titan's too muted ones) are worth it. Though at a little larger than 16 x 12, it isn't exactly portable.
Another interesting thing about these full reprints is that they reproduce the paper dolls that Raymond did along with the strip.

Lura "Vultan's favorite":
And last, but not least, Prince Thun the Lion Man:
