Linux Mint Startup Screen: Backgrounds

When Linux Mint (Cinnamon) boots to the login screen, a background is loaded, and if I recall correctly, back in the days of Linux Mint 17.x, the default background screen contained a graphic identifying the version of Linux Mint that was installed; for example, "17.1". I really liked that background; however, I can't find one in the collection that's included with Linux Mint 20.2 (Cinnamon).

Does such a screen exist, and if so, where can I find it?

Thanks, guys.
