Black and White Blues
It's been four years since your last Superman Showcase collection, and three since your last Superman Family*. I enjoy these collections a lot and I have supported this line by buying all the volumes you've released that interest me, reviewing them, and blogging about the ones I particularly enjoyed, but I'm tired of waiting, so I'm going to go read scans of the comics that would make up subsequent collections while I'm waiting for you to get around to publishing them so I can give you money.
*Okay, I see there's a new Superman Family due next year. If I start blogging about the stories in it now you can consider it a really early review.
