Query: great cover shot of Wolf - it's (c)1968 by S G Schoenfeld

you may have seen this dynamic, iconic and fully copyrighted photo of Wolf in many places, a number of which used it unintentionally without receiving permission of the owner, Wolf's photographer, friend and harmonica student S. G. Schoenfeld, who has since taken measures to correct this problem from re-occuring, and who has the story of this great photo and many others on his website www.howlingwolfphotos.com
