Did you Know there's a #NorthernIreland banknote with a secret #spooky #Halloween design? If you haven't seen it, this is the Ulster Bank Northern Ireland £20 note, which features not just #bats but #skeletons in homage to Derry/Londonderry's amazing Halloween celebrations. I couldn't tell you how many of these notes have passed through my hands before I saw this for myself. So get yourself a UV light and go looking for the wonderfully macabre detail, which is totally invisible to the naked eye.
