I just read an Announcement that John McInnis Auctioneers of Amesbury MA, will be auctioning John F Kennedy items.

According to the Announcement, the items come from the estate of Kennedy assistant and confidant, Dave Powers.

Here is a link to the Announcement from the Sports Collectors Daily website.

Below is a photo of the John F Kennedy signature on the photograph.

I do believe this to be a Secretary 1 "secretarial."
