Beautiful certificate from the Dundee Perth and London Shipping Company issued no later than 1880. This historic document was printed by G. Girdwood and has the signatures of the Company's Manager and is over 140 years old. The Dundee Perth and London Shipping Company (DPLC) ran steamships down the Tay from Perth and on to Hull and London. The firm still exists, but is now a travel agency. However, shipbuilding shrank with the closure of the five berths at the Robb Caledon yards in 1981, and came to a halt altogether in 1987 when the final 750 workers from the Kestrel Marine was shut down.
