Autographed DC twice up cover stock

The gallery title says it all...

My goal is to get any DC talent that could have done work for DC while they still used the twice up sized paper.

The best piece in my paper stock "collection" is a sheet of unused twice up DC cover stock... with the checkboard top.

I collected these signatures over a few years. There's a few more I'd like to get. And a few I wish I could have gotten but they are gone now...
