A Dixon bowl with Garibaldi

Thanks to Ian Holmes for providing the three shots below left of a bowl with Garibaldi. The three transfers all appear on typical Garrison Pottery plaques marked Dixon Co.  Do they help us in determining the date of the Garibaldi transfer? Was it made to commemorate his visit to Tyneside in 1854, or his visit to London in 1864?

The 'Gauntlet Clipper Ship' transfer is copied from an engraving in the Illustrated London News published on April 27, 1853.  Baker dates the 'New Bridge over the Wear at Sunderland' transfer as c1859.  So all we really know is that the bowl must have been made after c1859.

I still think 1854 is the most likely date for Garibaldi, and that the transfer plate had been in use for five or six years when the bowl was made. What might settle it is an item with a Garibaldi transfer, and a hand-painted date pre 1864!
