Mine was the USG Oswald Wirth, the one with the metallic backgrounds. I didn't know anything about Tarot at the time, and picked it out at a shop without knowing what I was buying. I couldn't make heads or tails of it, and left Tarot aside completely for a few years. Then I bought an RWS, but didn't really get started until I got a Morgan-Greer.
I ended up giving the OW away, something I regret, as I've learned to appreciate it in its own way when I learned more about it. I'll get it again sometime, but it isn't high on my list of priorities.
