Two new Charlton scans for the first time anywhere. CK is 1967. If you notice on the ifc it says International Copyright secured 1967 HOWEVER it does not say to whom. So it still does not carry a proper copyright and is PD
They were however getting there and the later issues are not PD
Would very much appreciate someone stepping up as an editor. You may notice many of latest scans crooked and uncropped. I have been a scanning machine without time for editing.
