a very short entry:
Polish Arms website has made available Polonica a free-to-download ebook of the rarest kind and quality, namely a 1943 photo album being the collection(in Swedish and Polish) of some of the Old Polish historic artifacts held at the Royal Armory in Sweden.
The description from their page:
Please note, that the Stockholm Roll is no longer in Stockholm, as painting was returned by Olof Palme to Polish care and custody at the Warsaw Royal Castle in 1974.
For the last month or so the Rolka (Roll) had been on display at the Royal Castle, but the exhibit closed yesterday.
