The LEAF black light poster depicts a single green Marijuana leaf which illuminates under black light.
A Black Light Poster is printed with inks that fluoresce under black light. The inks contain phosphors which cause them to glow under black light bulbs.
Originating from the psychedelic 60's and 70's black lights have seen a huge resurgence in recent years. Bulbs are now readily available from lighting shops and D.I.Y shops.
