1933 poster promoting the extraordinarily high levels of sun in the South compared to the rest of the UK. It's an interesting use of what we would now perhaps call a pixelated image (by John Hull Grundy), imitating a crude pointillist image. Personally I don't find it very effective.
The text reads:
"The further from this Poster the stronger it becomes
The further South you travel the stronger is the Sun"
The tag is "Southern Railway for sunshine at home and abroad"
