hello - all I can say about the signature it that it appears on several prints available sometimes on ebay, sometimes at auctions. Noboday knows who is/was behind this work. Here is an example of what I'm talking about : http://www.ebay.de/itm/320728053631?ssPageName=STRK:MEWAX:IT&_trksid=p3984.m1423.l2649 . As i own some of these prints I can tell you that most of the time the used papers are brandmarked with the logo "JCB" - which is the interessting part for me because of antother (unknown) artist I'm collecting ... I think both worked together for the same editor : here you can see the other one : http://ric-unknownartist.blogspot.com/ . Would be great if you find some more info one day and tell me ;-) ... good luck!
Thank you, I suggest combining forces in the Linosaurus trying to find the identity of these mystery printmakers who shared the same printing papers . Let me know what you think.
