NEPTUNES X B’APE

On the slippery slopes of Spain Zakka in the backstreets of Shibuya I came across this Eye Level Billboard for the Neptunes Single. Obviously tied intimately in with the B’APE empire and done up in this rather charming simple style that many Bathing Ape characters & japanese celebrities have be done up in (its a fine line sometimes.) Anybody know what nameless designer does these charactures for B’APE??
