Abstract

A display apparatus comprises a front stack of superimposed sheets which have cut lines and openings which form horizontally extending strips on the sheets. These strips are interleaved with similarly formed strips in a rear stack of sheets. In the interleaved position, upper portions of the front most sheets in the front and rear stacks are visible and are advantageously pictureless. To display a picture, one of the sheets in each of the front and rear stacks is lifted to expose their upper portions which carry segments of the same picture.

Claims

1. A display apparatus for displaying a plurality of pictures, comprising:

a front stack of at least three superimposed front sheets, each front sheet having opposite marginal portions, a plurality of vertically spaced horizontal cut lines extending between the marginal portions, and an upwardly enlarged opening at opposite ends of each cut line, said cut lines and openings dividing each front sheet into a plurality of vertically spaced front strips, the front strips being superimposed in the front stack of sheets in a first position of the display apparatus;

a rear stack of at least three superimposed rear sheets, each rear sheet having opposite marginal portions, a plurality of vertically spaced horizontally cut lines extending between the marginal portions, and a downwardly enlarged opening at opposite ends of each cut line, said cut lines and openings dividing each rear sheet into a plurality of vertically spaced rear strips, the rear strips being superimposed in the rear stack of sheets in the first position of the display apparatus;

said superimposed front strips being interleaved with said superimposed rear strips in the first position of the display apparatus so that lower horizontal portions of said front strips are covered by upper horizontal portions of said rear strips for displaying an upper horizontal portion of the front strips in an uppermost sheet of said front stack, and the upper horizontal portions of the rear strips in an uppermost sheet of said rear stack, in said first position of the display apparatus; and

each front sheet carrying at least segments of a different picture and each rear sheet carrying at least segments of a different picture, with segments of the same picture being carried by one sheet from each of said front and rear stacks, a sheet fron each of said front and rear stacks which carry at least segments of the same picture and which are below said uppermost front and rear sheets, being moved upwardly to establish a second position of the display apparatus which displays the same picture, the front and rear sheets being moved upwardly by an amount so that upper horizontal portions of the strips of the moved front sheet cover the upper horizontal portions of the rear strips of the uppermost rear sheet and upper horizontal portions of the rear strips of the moved rear sheet cover the upper horizontal portions of the front strips of the uppermost front sheet.

2. A display apparatus according to claim 1 wherein the uppermost rear sheet and the uppermost front sheet are both pictureless.

3. A display apparatus according to claim 1 wherein the picture segments on each of the front and rear sheets form a complete picture on each of the front and rear sheets with the same picture being carried by one of the front sheets and by one of the rear sheets.

4. A display apparatus according to claim 1 wherein each of the horizontal front and rear strips have the same vertical height, the displayed upper horizontal portions of the uppermost front and rear strips comprising approximately one-half of each strip.
