Thridgould was a major post card printing company - and the above price list shows how much it cost to get 500 copies of a post card published in about 1905.
One of the feature of the post card boom at the beginning of the 20th century was that many firms printed too many - and went out of business. Others found they had lines that did not sell well. In addition to printing cards Thridgould also obtained some of these surplus cards and did them up in assorted bundles at a knock down price.
