This is the best title I've been able to come up with. Pitiful, isn't it?
Some time ago- last year, I think?-, DC announced they were cutting down their TPB lines. Since then, most of trades collecting Golden, Silver, Bronze Age stuff and even 90's books have apparently been cancelled without warning. Or at least I've not seen new "Character A: The X Age" solicitations. I'm sure what some collections are still ongoing (I think a new Golden Age Batman Omnibus has been solicited? Or was it solicited and then cancelled?) , but most of them seem... gone.
It's a pity, because some old comics are really hard to find and expensive to buy. And some stuff has never been collected in an easy-to-read format.
Is there some book, series or character's run which has never been reprinted and you would like seeing collected?
Personally, I want more trades collecting Superman & Family's Silver and Bronze stuff. To my knowledge, most of it hasn't been collected. Maggin's Superman, Sekowsky's Supergirl... Sigh.
