The yellow CGC Signature Series label is given to collectibles that have been signed by someone of significance to the item. These labels will generally be issued only to items signed under the direct observation of a CGC representative. In select instances, CGC may accept signed books directly from the signer or publisher. The signatures are then authenticated by CGC with labels indicating who signed them, when they were signed and, in some cases, where they were signed.
After the collectible is signed in the presence of a CGC authorized witness, it is immediately submitted to CGC for expert grading and encapsulation in the state-of-the-art, CGC holder that bears the prestigious yellow label. Your collectible is then safely returned to you to become a treasured part of your collection.
