Learning about Margaret Calvert

After listening to a number of presentations about various graphic designers working at different periods in history, perhaps the most interesting part of it all was learning about Margaret Calvert, who was responsible for the designing of modern British road signs. ive simply never really given much thought to how the designs for modern road signs came about. learning that the vast majoirty of the signs were created by one individual seems somewhat interesting to me, im glad im now aware of this fact.
