In 1994, I purchase a reproduction of an 1840 lithograph West India Docks from the south east, 1840 by Parrott that shows a scene of ship repair at the Poplar Docks. In this lithograph, one can observe numerous ships and ship workers. Several riggers can be found high in the rigging of the closest ship and shipwrights can be seen in the foreground making repairs. The ships have been lifted onto a dry dock for the repairs. In the background, there is a draft horse for pulling material and what appears to be numerous men straining to pull a rope to raise a load of material onto the ship. It is an excellent representation of the activities of our Poplar ancestors.
A way to view the Lithograph is to do a web search on the phrase: View of West India Docks from the south east, 1840. This will lead to several art studios offering to sell this print.
The Wikipedia article West India Docks includes its history and a number of photos.
