ABSTRACT:
A device for marking a page of a book and for indicating the number of such page comprising a first sheet of thin rigid opaque plastic material formed in a generally rectangular configuration with long parallel side edges and short parallel upper and lower edges. A second sheet of thin rigid opaque plastic material is formed in a generally rectangular configuration with long parallel side edges and short parallel upper and lower edges, the first of the sheets being formed with a plurality of equally spaced rectangular windows formed between the longitudinal center line of the sheet and a second long edge. A plurality of transparent rigid opaque plastic circular disks are provided, each of the disks being formed with the numbers 0 through 9 adjacent to its periphery for sequentially being positioned adjacent to the windows. A rivet extends through the center of each circular member and through the first and second sheets to allow for rotation of each circular member independent of the other circular members to bring a number into view through the window for indicating the page number of a book being marked, a minor portion of each circle extending beyond the space between the sheets to allow a user to rotate each circular member to thereby change an exposed number.
