First Century Mark Allegedly Offered for Sale

I was recently asked to contribute an article on the "first-century" Mark fragment (P.Oxy. 83.5345) in the journal Early Christianity. Toward the end of that published piece, I wrote:

"There is one important question that remains unanswered regarding this papyrus. Despite the EES’s statement to the contrary, why have multiple people, including Steve Green, president of Hobby Lobby and the Green Collection’s benefactor, admitted that the Oxyrhynchus Mark papyrus was for sale at some point?"
 
It is now fairly evident that “first century” Mark was offered for sale. Please see the THIS blog post by my colleague, Brent Nongbri, who relays breaking e-mail correspondence from Mike Holmes. 
 
Essentially, if the allegation in the e-mail is true, it indicates that an Oxford professor (Dirk Obbink) intentionally tried to sell papyri belonging to the Egypt Exploration Society (EES) to the Green Collection. 

​This is not to be taken lightly.  I am very curious to see what actions the EES will take here. It seems altogether criminal, in my opinion. This is a sad state of affairs indeed, but a conclusion (if proven true) that many have already drawn. 
 
This news is part of a much larger web of conversation and debate around the manuscript acquisitions of the Green Collection, which I have posted about here, here, here, and here.
