I didn't buy any Profiles in the 1970s either. I would drool over them in hobby shops - back then, full-color multi-view illustrations were a lot harder to produce and therefore rare. When it became possible to buy them in compiled form via the internet, I did so, and now have all of them in hard copy, including the last several loose ones that were never published as a bound collection. They are still useful references. Many of them can now be downloaded at the
rclibrary site.
