CGC does grade magazine-size books. However, CGC does not grade treasury-size books as their size exceeds even the largest available CGC holder.

Yes, under the following circumstances: CGC's prestigious Signature Series label (yellow) is applied to comic books that have been signed under the direct observation of a CGC employee or a select CGC authorized witness, or in select instances where CGC accepted signed books directly from the signer / publisher. The signatures are authenticated by CGC, and the labels indicate who signed the book, the date it was signed and, in some cases, the location where it was signed. If a book is signed without a CGC representative present, it will receive a Qualified label (green), and will receive a Qualified grade. No authentication of signature is provided for books that do not have a CGC Signature Series label. To learn more about CGC Signature Series, visit https://www.cgccomics.com/signature-series/.

CGC does not certify sealed poly-bagged books. To have a poly-bagged book certified by CGC, you must remove the book from its poly-bag or send written approval authorizing CGC to remove it. The words "Poly-bag removed" appear on the CGC label.
