Don`t know why I didn`t think of this before !! I worked for a screen printing company at one time !! You said it was cut out ?? Could be a plate from screen print,, they are burned into a plastic like sheet, then the colors and figures are layered, one sheet at a time onto the surface being printed and each color is applied with an individual sheet !! Since most all of the art is on the sheet this may have been toward the last of the production so whoever was doing the printing could check and see that all the sheets were done properly and nothing was missed !!
