Zu, how much is this drawing worth (in NCr $)?

Written in the drawing: 7. When, however, a thousand years are completed, Satan will be released from his prison, / 8. and will go forth to seduce the nations that are in the four corners of the earth, Gog and Magog, in order to gather Them for the fight. The number of these is like the sand of the sea. [Reference to chapter 20 of the book of Revelation]
