Hi everyone! 
Ever wondered what Plone looked like back in 2003? No need to hunt for old screenshots anymore. You can just run it.
I wrote a post about it:
The short version: I'm working on a project that upgrades a Plone 2.1 site to Plone 6.2 with Volto. Getting Plone 2.1, and the ancient Python it needs, to run on a modern OS is a challenge, and we had no container images for anything older than Plone 4.3. So I built them.
There's now one image per release series, all the way back to Plone 1.0. Each one has a -demo variant with a Plone site already created. Pick a year and off you go:
docker run -it --rm --platform linux/amd64 -p 8080:8080 plone/plone:1.0-demo
Open http://localhost:8080/Plone and log in with admin / admin. Swap 1.0 for 2.1, 3.3, 4.2… and enjoy the nostalgia. 
(Please don't use any of these in production! Besides being old, they are not supported and have known, unpatched security issues. They're meant for content extraction, migration rehearsals and archeology.)
A nice side effect: this work also led to the proposal to standardize the names of our container image repositories. The rename is done, and the old plone/plone.docker repository is now plone/container-historical, which is where these images live. Thanks @gforcada for the name!
Part 2 will cover Plone 4.3 to 6.2, as soon as those images get their -demo variants too.
If you take one of them for a spin, tell me which version brings back the most memories. Did your Plone journey start with 2.5? 3.0? Screenshots are very welcome!
p.s: And, of course, to please our good friend @polyester: We do have Hello Kitty!
