I got Adobe Photodeluxe 1.0 CD which my Dad gave me (due to 1996 .-.). It's intact but I no longer has the case of it, and apparently they actually used cd-keys back then, woah.
It is literally what Photoshop came from, the very first prototype (And there were made up to 4.0, till 2002 after that Photoshop Elements came out.).
