Print publisher, of a wide range of genres and over a long period of time. Prints published in 1822 are lettered 'Repository of Wit & Humour', 26 Haymarket, London; but according to Dorothy George, all prints dated before 1824 are reissues of 1824 or later. In the 1840s-50s also ran a lithographic printing workshop at 70 St Martin's Lane; this sometimes described as McLean & Co. Still active in the 1870s (see below).
Some of his prints bear a circular blindstamp and lettered 'Thos.McLean' (recto).
Part 22 of Tallis's London Street Views 1838-40 shows T. McLean Printseller & Publisher at 26 Haymarket, on the eastern side just north of Panton Street. From 1866 the business was at 7 Haymarket. The business was taken over by the son, Thomas Miller McLean (q.v.), probably with an overlap, 1865-75.
