Where to find old Mac OS desktop wallpapers

Hi, I recently did a hard reset on my Macbook Air 2017. When reinstalling, I think my Mac started up with Mojave I assume this as that would be around the time the Mac was produced?

Either way, I set up a nice desktop wallpaper from one of the OS generic ones. Since then I have upgraded the OS as I realised it was too old and some things were no longer compatible or could not update.

I have now seen that this wallpaper is not part of the current OS generic wallpapers. I am really keen to get this wallpaper back as the current ones on Monterey I am not a fan of - I have tried looking on google but no luck so far, can anyone help please?
