Transformers 1 CGCS 6.0 Signed with Sketch by buying Bill Sienkiewicz

Product Name: Transformers 1 CGCS 6.0 Signed with Sketch by buying Bill Sienkiewicz
Transformers 1 Comic Book with Signature and Sketch on its Cover by Bill Sienkiewicz. Graded with a 6.0 from CGC Signature Series. As expected for a 6.0, this book has condition buying issues (please see photos). The plastic slab it is encased in is in good condition. No COA, but in my opinion the CGCS slab is a better sign of authenticity than a COA. Key Book! Origin & 1st Comic Appearance of Autobots and Decepticons!.
