Other forms: centerfolds
A centerfold is the picture printed across the two middle pages. The magazine centerfold, a centerfold spread, pull out the centerfold.
The middle pages are the only ones that can carry an image across the fold without the binding cutting through it, which is why the biggest picture goes there. The word is chiefly associated with pin-up magazines and carries that association everywhere. This is the American spelling; British English writes centrefold. Note the design term gutter, for the fold itself.
