First, is this promo pic letterpress stamped? And even if or not, are the signature styles typical? I have my opinion but I welcome to hear from Mark, Jack, Josh, and the usual suspects.
The second question is because I am so amazed regarding how many preprints are offered on ebay that are sold as such, ie clearly sold as preprints but for example, the Morrison is a preprint of a fake Morrison. The point being, if someone is to sell a preprint, why not make sure it is of an authentic Morrison unless thre are some copyright issues?
