Rare original vintage advertising poster: Shell is Nature's Mixture. Shell Spirit is singularly rich in Natural Benzol in correct proportion with the petrol to assure perfect combustion. Being a great engine cleaning agent there is no risk of sticky valves or a fouled engine. Every drop is converted into power, hence the high mileage of Shell. Reduce friction losses by lubricating with Shell Motor Oils. Great early black and white illustration by Edmund Joseph Sullivan (1869-1933) depicted two ladies sitting in a nature scene surrounded by trees and flowers while pouring liquid into a giant shell from large jars, the text at the top and below. Fair condition, tears in left and bottom margins, creases and folds, irregular edge on the right side.
