1870 Rock & Co. London All Seeing Eye Over Globe Letterhead Engraving

I just think this graphic with all seeing eye casting its protective rays upon ships traveling the perimeter of the globe and a train crossing along the equator is really fantastic, produced by Rock & Co. London, 1870. Rock & Co was a print and playing-card publisher first established as  "De La Rue, Cornish & Rock" in 1833, which produced the now famous De La Rue playing cards. Seems to me his letterhead engraving could provide the basis for a pretty excellent tattoo, or all sorts of things; just excellent!

Paper size, as folded in half: 7 1/4" x 4 7/16. Very good condition but for a small stain at top left edge.
