This is a CGC graded 9.8 copy of Sheena Queen of the Jungle #1, from 2017. The comic features the virgin retailer incentive cover art by Mr. Campbell and is signed by him. The qualified grade is due to the fact that CGC does not verify signatures sent in to them from previously signed books.
This comic does have the COA with it that states it is signed by Mr. Campbell as #79 in his signature series. The CGC census lists this as the only comic graded at this level, but I think they are wrong. I saw another but it was labeled cover J whereas this is labeled cover F.They look the same to me.
