These are large 8.6" x 12" square-bound reprints published by Panini in the UK. They reprinted stories from the "Marvel Age" reboot, i.e. Marvel Age: Spider-Man and other associated titles and one-shots.
The advertising was replaced by fact-files, puzzles, and coloring page. They were priced at £4.99 which seems a fair price given that these were large, bright, attractive, and well-made.
