Introduced in 1963, the Cherry line is marked with the WG. The piece shown is the CH-9 Lilac Opalescent cookie jar with two handles.
The cookie jar has been reproduced in many colors. Originals will have a 'rayed star' on the bottom, with a circle in the center of the star and the 'WG' logo inside of that. If any of these 3 items are missing, it is probably a reproduction.
