Hello all, I am new here but not new to Tolkien collecting.

I have two questions:

For the CoH Deluxe Edition, first print - I've seen for sale some signed by CT and AL on a plate, some signed only by AL on the title page, and some un-signed. Are all these official versions of the book?

For the S&G Deluxe Edition - know anywhere where I can find a first print of this one?!
