Copy of 4% of the Period III Series I mortgage bond of the Land Credit Society in the Kingdom of Poland.
This copy comes from the book "History of the January Uprising 1863 - 1864", by August Sokolowski, published ~1910. In the book it is an insert, between pages 144 and 145. All pieces coming from Sokolowski's book have the same No. 138,625, a blank reverse page, and are printed on paper (and not on parchment like the original pledge letters of this issue).
