Well, narfstar, as I'm still awaiting clarification on the Masterman comic from my pal, who insists he is getting somewhere with it, I'm probably the least reliable person to ask. That said, I have an original Kat comic - #8 (and an original Pimpernel, #4 plus a couple of Pimpernel facsimiles as well as Dick Bos. The originals can be a bit fragile) Problem is that De Kat reappeared in a magazine sized adventure a few years ago - new story and art, and very adult. So the original stories could be pd but not the character. Dick Bos, for example has been reprinted in recent years and is not pd, as far as I know. As with many old, really obscure British comics, most people in Netherlands, incl. collectors and comic shop owners, do not really remember this stuff. But copyright law is such that it only takes one person and you're in soapy bubble.
