Royal Society for the Prevention of Accidents poster This poster was designed with Eric Lombers and is signed T. Eckersley and E. Lombers. It features the slogan 'motorists observe/ pedestrians use/ the proper crossings' , spaced at the header [black], along the base of the image [white] and at the footer [black]. The image is reminiscent of warning road signs, it is a triangle that's red on two sides and black on one. The colours merge with each other. One the black side are white dashes like a crossing. The triangle has a solid yellow shadow. The background colour is white. See TE/1/21 for other commissions by the Royal Society for the Prevention of Accidents. 1946
