Jaguar Game Carts Question

[smokenmirrors]

I have bought an atari jag power drive rally cartridge with a plain back, up until now all Atari Jaguar Carts I've come across have had the Atari logo and name indented on the back of the cartridge. Is this rare or are all power drive carts like this?

some are black and dont say Atari. Mine is just like that to, and i have other games for the Jag that are also like that.

Not so rare then, I was just suspicious as I bought the cart with a lot of other stuff that seems to have come from a PR company that went into liquidation. I thought it might be a copy not meant for general release, but obviously not. Thanks for the help.
