This is a discreet series of lglass plates which comprise both original negatives and copies of original photographs or lantern slides of people in the maritime industry, largely captains, masters or ship-builders. The negatives were probably made by, or for, Harry O'May, either from photographs he had in his collection or had borrowed from other sources. In some negatives the original photographs can be seen pinned to a board in order for the copy to be made. Harry often gave public presentations using lantern slides for illustration e.g. "Ships of Other days: Talk to the Hobart Rotarians", Mercury (TAS), 20 July 1934.
A number of the original negative boxes were labelled "sea captains" and there are some negatives of general interest included.
These records are part of the holdings of the Tasmanian Archives
