The design for the robot itself comes from the 2005 (not the 1981) movie. (trailer - Marvin appears at ~1:10)
But if you mean this particular style of image with this font and such, that I don’t know - perhaps some stickers or tshirts or such became popular to share, it does look nice:-).
On seeing this design twice makes me question where it comes from. Did somebody make an illustration for the books or how did this happen?
