Back when I started seriously collecting back in the early 90's foil, holographic and prismatic covers were all the rage. Then, just like that, they stopped. When I asked Marvel why they had stopped producing these covers they told me that they couldnt afford to keep on producing them. These days some comics are being produced with multiple variant covers. House Of M #1 and Civil War #1 both have 5 covers and every week there are more and more variant covers being announced. Marvel must be making an absolute fortune from the sale of these variants. Surely they could start producing some Foil covers? Even if it's just for anniversary issues?
