I've been reading a bunch of 1993/4/5 era Sega Powers and Megas that I got off eBay, and I found something decidedly interesting.. ads (top and bottom of an ad - damn UK mags and being wider than A4) and, in Mega, an article about these two carts for the price of one offers.

The ad and article make them look like they're specific packaging - has anyone out there seen these?
Mind you, a friend of mine in the UK on IRC suggested they might have just been the original two boxes for the games in question with the Telstar bit shrinkwrapped around 'em.

I'm curious because I've never seen these before, and if they are unique packaging - the two carts in one box, with a Telstar inlay, I'd kill you all for the SMS ones mentioned at the bottom of the ad
