The first figure is from the Ministry of Ungentlemanly Warfare pack. He's simply painted with everything except the face and tie just blocked in with no highlighting at all.
The next guy is also by Artizan but from the Enemy Agents pack. he's had some very basic highlighting added to his black clothing. This looks awful in the photographs but is hardly noticeable in real life. In which case it's probably not worth doing!
I'm thinking my Pulp villains might be some kind of international conspiracy of influential men preparing for "the forthcoming war against Bolshevism". I quite fancy the idea of the Heroes' opponents including the Gestapo, Japanese agents, and elements within the British Establishment.
