A first image is printed on the first surface of the glass panel and a second image is printed on same first surface of the glass panel and at least partially overlapping the first image. The second image printed on the first surface and at least partially overlapping the first image forms at least partially opaque imbedded into the glass panel image that when covered by a fluid becomes transparent to reveal the first image printed on the second surface of the glass panel.
