The prints of J.H. Lynch were a ubiquitous part of the 60s/70s. Strangely though, for an artist who's work was reproduced by the thousands, his identity remained a mystery. That was until Mario Klingemann set up
www.jhlynch.org, and managed to track him down. His site remains one of the best sources of information on Lynch prints to-date.
As luck would have it, I manged to pick up my "Woodland Goddess" in Ballarat for $30 back when Lynch prints were selling for $80 in Melb. Last I saw (Lost & Found Market) they're up around $200 now!

"Woodland Goddess" by Joseph Henry Lynch, pre-1965
