Apparatus for visually registering indicia

For use in perpetual calendars and other uses to visually register indicia apparatus having rotatable members whereby relative rotation of the members visually registers indicia on one of the members, comprising:

• a circular member having a supporting wall and a first top surface bridging the area between said wall,
• said first top surface having an area of a first color, and interposed in said first color and of a lesser area, a second color distinct from said first color,
• the area of said first color extending at least in a peripheral band around said first top surface spaced by said second color,
• a circular cap rotatable on and overlying and surrounding the top and wall of the circular member, said cap having a second top surface having an area of said first color overlying said area of said first color on said circular member and extending at least in a peripheral band, there are a plurality of said circular members and said caps concentrically arranged, said plurality of circular members are joined and said caps are fitted to be independently rotated on respective circular members, and
• peripherally arranged transparent indicia formed in said second top surface in said area of said first color thereon whereby relative rotation of said members will cause a portion of said indicia to overlie and register with said second area of color to visually direct attention to said portion of said indicia the respective second areas of color are radially aligned.
