This trade card features a very large anchor, supported, presumably, by the figure of "Hope". Nearly one hundred years later, 23 St. Mary's Axe was still associated with nautical printing, as this is where the 'Marine Engineering News', offering "Advertising Medium for the Shipbuilding and Engineering Trades", was published.

It is likely that the "T. Colley" advertising his skills in this card was Thomas Graham Colley, who often signed himself in this way. He was the engraver of a number of satirical political prints of the 1780s, a "prolific etcher and publisher of his own works. Presumably the Thomas Colley who married Mattina Darly [engraver of similar cartoons] on 11 October 1778. Full name given by 1781 plate of the death of Major Peirson. Many of his plates jointly sold with E. Hedges" (BM). Other, later addresses associated with Colley are: Clare Market, London (1780); 288 Strand or Strand, London (1780-1); 257 High Holborn or High Holborn, London (1781); Rolls Buildings, Fetter Lane, or Acorn Court, Rolls Buildings, London (1782-3); 3 Union St, Portsmouth (1793).
