2 Claims. (01. 41-33) My invention relates to a method of decoratcellulose material, or the like, and press it firmly ing articles, including sign globes for out of doors, against the exposed decalcomania, by a roller or such as those of the canteen type, and other squeegee. The water is thereby squeezed from surfaces-especially those intended for outside between the sheet and decalcomanla and the use. sheet of course caused to flt snugly in place. .0

The globe may then be heated as heretotore explained, and this heating will not only effect a firmer union of the transparent sheet with the decalcomania material, but will-also cause the decalcomania to adhere more firmly to the glass.

It will, of course, be understood that it is not essential for the transparent sheet to adhere to the face of the globe throughout the entire surface of the sheet, but the sheet can be pressed snugly against the globe and the edges thereof cemented or otherwise secured to the globe.
