Five quid was a decent amount of dosh then. The design wasn't carried on to the smaller note, by then BoE decided to put HRH on the fiver - which really was a shame. British banks, particularly those in England had a tradition of sorts of NOT having a portrait or even cipher of the monarch on notes as a bit of a superstition - a couple of Scottish banks didn't follow such beliefs - and failed spectacularly - City of Glasgow bank was one in 1878 that had had small portraits of Queen Victoria on their notes. A similar pattern followed in British North America - the banks like Westmoreland Bank that had portraits of Queen Victoria bought the farm - the only exception to the rule was Bank of Toronto which kept portraits of Queen Victoria and Prince Albert on their notes into the late 1930s.
