Literally.
In my college physics lab was a massive poster that I have been utterly unable to find since I learned to use the intertoobs to shop for stuff and things. The poster was about the size of an old school projection movie screen, maybe twice as wide as standard. It showed a series of 3D perspective based maps of the universe, starting with Earth and progressing to the observable universe. It was one of those simple and utterly defining things in my life that really put it all in perspective. I have looked off and on for one of those wall sized posters for a while now, and only tonight have I found the series of images that were the poster. Its a link to a wikipedia image.

Those were the graphs on the poster(‘s?)and it contained perspective (scale?) blow-ups and other information such as relative size and distance axes. I dont know if this was a custom thing, but I would absolutely love to have a wall size copy of that poster.
If there is anyone who went to WSU in the late 90’s who saw that poster or anyone with actual internets ability who could point me in the right direction, it would be much appreciated!
Thank you.
