Harley Quinn Prelim

Found this splendid little A4 pen-over-blueline piece recently, lurking in a folio, realised I'd not posted it on CAF, felt it positively rude not to now do so (given that it's evidently (or at least I'm assuming it so to be) a 'pre-winking' prelim to one of Ben's most iconic images, part of that 2016 triumvirate of 'DC Universe Rebirth' full-face covers - Batsy, Harley, Croc - that very much brought his work to a wider audience).
So here it is.
An eBay purchase as I recall - and we aficionados of Ben's work know, his pieces pop up on eBay depressingly seldom.
