Got my first batch of Mighty World Of Marvels and Titans UK Comics...Clem, I see what you mean about the Titans books. There are a lot of pages with "Bullpen" artists either doing a new splash page so the book evens up in it's side by side pages inside or it's Bullpen artists re-imagining or lightboxing some original Marvel pages. I did find the Titans centerspread posters interesting. There's a nice Vision done by Nasser and Adams in one of the books.
I have a few earlier issues of Mighty World Of Marvel where the green ink really does add to the black and white pages. Especially in the Hulk stories. I think moving forward with collecting these I think I will stick to the regular books and stay away from the landscape books like Titans. Was Titans the only book to do landscape style books??
