F.P. Becker (Omnigraph [steel] engraver) – George Virtue (publisher).
London, 10.5 x 8.5 inches, depicting external boundaries for the pre-Partition Polish-Lithuanian Commonwealth, but internal boundaries that correspond neither to pre-partition boundaries nor to Russian guberniyas. Mid-19th century Poland’s boundaries are visible, but often outline-colored to make them indistinguishable from other boundaries. Versions are all from Virtue’s edition of Barclay’s “A Complete and Universal English Dictionary,” published 1841 to at least 1850
