Wonderful helmeted bust !
Almost looks like an Art Deco style Flash Gordon portrait.
With the excellent spear and shield added in for extra I can see why you may have paid a bit extra for it. Some things are worth paying for !
Early London is always good to have around.
I finally arranged my own London Folles by portrait style.
I bought way too many last year.
Much to my great satisfaction I actually found an obverse die match of Galerius as Caesar.
Joy !
