i went to bookoff last week after AX is over, and found a ONE PIECE COLORING BOOK. so i scanned all the pages, since i figured there are a few people out there who want to practice coloring with photoshop but doesn't have good, clean, high resolution one piece scans that are only outline.
this zip is 25MB big, they're about 2000x3000 pixels in size, scanned at 300dpi, and leveled. 32 pages total. the scenes are from the davybackfight arc, including some aokiji stuff in there.
download zip here: http://e1n.kefi.org/MANGA/OPColoringBook.zip
here are a few pages from the coloring book, in reduced quality to reduce image size. the one in the zip will be much, much bigger than this.
