The TV in this ad is only the third porthole I see here in Brazil ( I happen to own one of those three, but mine really is in a sad shape, I only bought it because of it's rarity ). Mine and the one in the ad I posted have the plastic mask around the CRT broken. I don't remember seeing pictures of these TVs in the USA with the mask broken, why they broke here, maybe it was because of the climate?
