wait, are you OP? or did you happen to find a high res version of the same paper-copy picture that OP supposedly was given 30 years ago and then scanned and then threw out. or did OP make it up? or is OP just a bot?
maybe i'm a bot.
anyway i used to call into BBSs back in the early 90s and the thing I'm remembering is that they survived mostly on donations, and now that I am seeing the infrastructure that supported those systems and recalling the price of hardware back then I'm starting to second guess everything I thought I knew.
Many sites including Google offer reverse image search. You give it an image and it gives you a list of places it appears, sometimes in higher resolution or with more context (or different context, which can be interesting).
Rachel says she had the photo as a postcard. It's likely that more postcards were printed, and that other people had owned those copies, rather than people being bots.
