This is the earliest known drawing of the Underground's standard bullseye design, as re-designed by Edward Johnston in 1925.
The diagram shows Johnston's design guidelines for the symbol, including the exact proportions, measurements and colours to be used with the 'pecked' Underground lettering. At the bottom are the registered design numbers for two variations of the sign.
The symbol was known as the roundel after 1972.
