This old archive is a collection of very old UNIX bitmap wallpapers.

These should be quite useful if you wish to set up a retro desktop and wish to have a retro tiling wallpaper as well.
Also, I have a nice collection of all Windows `98 wallpapers.
https://securitronlinux.com/linux/maps/Windows98.rar. That should also be very useful when setting up a classic styled Linux desktop. They look very cool and would be fun to use on a modern desktop.
These are great to have in your collection, they are a part of history.
And finally, a collection of Windows Vista icons that work with the Linux Mint MATE desktop: https://securitronlinux.com/linux/files/Vista.tar.gz.
That would work very well and look awesome.
The image to the right should be very familiar if you have ever used Windows `98 before. it involved a lot of reboots to get everything working right.
