Printers' International Specimen Exchange
Conceived around the time of the Caxton Celebration of 1877 , it was an ambitious expansion of a "Specimens" column then appearing in the "Paper & Printing Trades Journal" , a widely read trade publication issued by London printers and publishers Field & Tuer and edited by Andrew White Tuer .
