same here: there are hundreds of paintings from the seventies where I don't have a record at all. And those that I do, only scans from analog photos that are not very suitable for poster printing. Some of my most popular images actually come from that time.
Coming well prepared: yes, that I was alerted to by Snezana. So there, I could relax - I did some drawing there also, and the Pigmalion guest book entry you likely saw in one of my posts. That book was started just new, with this colony, so our group were the first ones to contribute to it.
