Red and cream silk kerchief with printed decoration in black and additional colours of yellow, red and grey applied by hand to the central illustration. The illustration of whole tunnel that decorates the border is similar to one by William Westall. The square central illustration of the interior of the Thames Tunnel is an illustration by James D. Harding. This would have been a more expensive souvenir in comparison to the other commemorative handkerchief in the Brunel Museum collection (LDBRU:2007.2) due to its higher quality and the more laborious production process.
