G'day again rich-joy,The artwork culled from my old Singabout files does include a few useful drawings of singers ... from the first Journal of Australian Folk Lore (1956 - 1967). As I am the current Publications Editor for the Bush Music Club (for the past 30 year ... ! ... ? ...!) I use these quite often. I would not mind some of them seeing the light in other reasonably appropriate places.
I also have a lot of good, public domain, stuff found in the IMSI Masterclips graphics files (mentioned above by "Bat Goddess", who must have their 250,001 image collection (3 CDs). I have this, plus their 500,001 image lot ... 28 CDs! (But lower res. images of the Dover stuff!)
PM me an e-mail address and I'll run a few (relatively low res. versions of) images past you to see what you are after.
Regards,
Bob Bolton
