Professor X is trying to rebuild memories of his past using other people's minds.

In mid-June 2022, there were 36 gradings recorded for the confusingly named "Retailer Incentive Edition" (noting "Partial Sketch cover" in the label comments) in the CGC Census with 11 in the top grade of 9.8 (near mint / mint). Note that the actual 1:10 retailer incentive edition is called the "Secret Variant Cover".
At that same time, there appeared to be no gradings recorded in the CBCS Population Report.
