.~ Illusion caused by apparent change in color, printed matter, surface texture, or rigidity
DEFINITION
Classification: 472/72
Illusion caused by apparent change in color, printed matter, surface texture, or rigidity:
(under subclass 57) Amusement device wherein the illusionary effect created by the device involves (a) altering the external hue of an article, (b) altering the indicia located on the surface of an article so that the new indicia convey different information (e.g., a strip of newspaper having newsprint thereon is transformed into paper monetary currency), (c) altering the structural appearance of the surface (other than hue, shape, or form) of an article, or (d) altering the structural stiffness of an article; whereby the means by which the device alters the article is not apparent to a person observing the transformation.
(1) Note. The indicia (i.e., the printed matter) located on an article may take any form. For example, the indicia may be embossed or engraved on the article rather than being merely printed thereon. The information conveyed by the indicia to a person viewing it may also take any form. For example, the indicia on an article may denote the function of the article (e.g., the indicia on a piece of paper may denote it as being an item of paper monetary currency or as a grocery shopping list).
