I believe this is not an error but is in there purposely. It is artistic 'license' used as a symbol for a tower to represent a city's industrial growth etc. All my stamps have this marking as well.
Is it also "artistic license" that there appears to be no wheels on the landing gear toward the front of the fuselage of the plane? Or are those vertical lines supposed to represent something else?
