A food package insert comprising a multi-part structure having at least one removable edge portion. The multi-part structure includes an oil and grease resistant cellulosic support web having first and second exterior surfaces, first and second facing interior surfaces, and a support web edge portion disposed adjacent the removable edge portion thereof. At least one hidden image is imprinted on one of the first and second facing interior surfaces. The hidden image is printed in a first color and a second color is imprinted over the first color in a pattern sufficient to substantially hide the hidden image. A colored film insert is attached to the fixed edge portion of the web between the facing first and second interior surfaces. The colored film insert is printed with the second color and is at least partially transparent for revealing a hidden image printed on one of the first and second interior surfaces.
