I picked up these two Cal-Neva Lodge chips from Bud Meyer on Friday at the Reno show. Bud dates them to 1941 and said about 30-35 were found - two black, seven yellow and the rest maroon. I've seen Cal-Neva advertising material from the '40s that referred to the "Castle in the Air" slogan, so I believe the 1941 date to be correct. There is no denomination listed.

Does anyone have these in their collection or know anything about them, such as whether they were roulettes, promotional chips or something else? Any help would be appreciated. Thanks.
