Now it gets complicated. After a little more digging, I was wrong to attribute this to John Bartholomew (I found that attribution by an internet search). It does indeed appear as an illustration in Thomas C. Jack’s “The Gazetteer of the World” published in London in 1887 and Bartholomew did produce map engravings for the work (which I believe may have been printed in colour). But it seems he didn’t produce the engravings for the other monochrome illustrations. That seems to be a mis-attribution (but you can see how it might have arisen) as evidenced by an earlier example of the engraving in the British Museum:
They describe it as a “book illustration” for William Brockedon's "Finden's Illustrations of the Life and Works of Lord Byron". The plate has “Drawn by J.D. Harding from a sketch by W. Page” and “Engraved by E. Finden” above the title “Bay of Naples” with “London Published 1833, by J. Murray & sold by C. Tilt, 85, Fleet Street” below. It's said to be a steel engraving, not a wood-block. The size (including the border) is given as:
Height: 160 millimetres (sheet; trimmed or cut)
Width: 230 millimetres (sheet; trimmed or cut)
William Brockedon (1787-1854) was a Devonshire Painter, draughtsman, illustrator and writer who studied in London, travelled widely and authored (edited) the work on Byron containing Finden’s engravings.
James Duffield Harding (1798-1863) was a London painter, draughtsman and printmaker.
William Page (1794-1872) was a British landscape painter who travelled extensively in Europe.
Edward Francis Finden (1791-1857) was a London line and stipple engraver and printmaker.
John Murray was a London publisher established in 1768 and still in business under that name until 2002.
Charles Tilt was a London publisher and printer from c.1813-1841
Both books containing this engraving were published as three volume sets in “8vo” or “Octavo” size, for which the pages are typically approximately 160 × 230 mm. The illustration itself is around 90 x 135 mm, excluding the border and in moncochrome, not colour. Those typically sell for around $25-30 since you could buy a a full original set of either of those works with their dozens of plates for a few hundred dollars or less.
There are modern prints available, reproduced from the Granger Collection but upsized to 18 x 24 inches priced at $33, or 24 x 36 inches priced at $66. Again, these are monochrome.
Also, since the copyright has long expired, both books have been reproduced from scans of the original volumes in modern times in both hardback and paperback, notably:

Those will have the original illustration in monochrome and I don’t think they were printed on the quality of paper apparent in your print.
Sacrilege though it may be, as I said, books like this are often deconstructed to get the illustrated plates which may then be hand colourised to enhance their appeal. I have an acquaintance who is an antiquarian book dealer who makes a substantial proportion of his profits by doing exactly that. He cuts the engraved prints from books that are damaged or have a low profit potential, colourises them himself and frames them for sale.
Depending on the size, I still suspect that’s what you have, with the colourisation added at an unknown date.
