The series comprises commercial post cards depicting places and objects either purchased by the Walkers during their travels or received as greetings cards from family and friends. They appear to have been maintained as part of the photograph collections (AA 357/02) and have been seperated for control and retrieval purposes.

Occasionally it is not clear whether a print is a commercial card of a Walker photograph printed on post card printed paper.

Indexing.
An index entry in the "Finding Aid" should provide access to all relevant references. While the 'Details' column for each "Inventory Item" is entered in 'natural language', constraints in the indexing system may distort the text with additional punctuation or searchable index strings. All personal names and locations contained in annotations have been indexed, however, names may be misspelt and index system anomolies may provide some unexpected results.
