Children's publisher Candlewick Press will release The Amazing Spider-Man Pop-up in April with three more Marvel pop-ups planned for over the next three years.  The Marvel True Believers Retro Character Collection will excerpt original Marvel material from the '60s and present it in elaborate pop-up form, complete with metallic inks and slide-out character fact files.

The True Believers line is targeted to readers ages 5 and older, with 16 pages and a $24.99 cover price.  An X-Men pop-up is anticipated for fall 2008.
