Cardboard tickets, which were called Edmondson tickets after their inventor, were used on Latvian railways for almost a century. Each station had a special cabinet where cashiers deposited the tickets, which were pre-printed and cut to 5.5 x 3 cm.

At the dawn of the railway era, tickets were handwritten on a piece of paper. In 1838, the English railwayman Thomas Edmonson started using pieces of cardboard with the names of the departure and destination stations and the ticket price printed on them. Upon selling the ticket, the cashier had only to fill in its number, thus significantly reducing selling time. There are several hundreds of this type of tickets in the holdings of the Latvian Railway History Museum, as well as ticket cabinets from various periods: larger ones that were placed on the floor, and smaller ones that were hung on the wall.
