Was the famous Trivial Pursuit misprint real?

I've searched the internet for a picture of an actual card, but came up with nothing. Was there every a card that said "The Moops" invaded spain the eighth century?

That took about a minute to find. You're lazy I tell you! What's wrong with using Google, eh?

Yeah I know Wikipedia's not an ideal source and that particular sentence is unsourced, but... why does it matter anyway?

I saw the wikipedia, I wanted proof. If one of the writers could spot it, surely someone else would have. I want to see a photo of the card itself.
