ABSTRACT:
A display support in which a back wall is provided with a pair of horizontal walls; and a front concave wall which is a smooth concave curve without any folds therein extending continuously in an arc from the outer edge of one horizontal wall to the outer edge of the other horizontal wall. A fold line is provided in the back wall transverse to the back wall and parallel to the horizontal walls. By providing this fold line in the back wall at a specific location which is substantially equal to the sum of the lengths of the two horizontal walls and the back wall minus the linear length of the front concave wall divided by two, a minimum of indenting of the back wall is obtained in order to obtain the smooth contour of the front concave wall.
