Real Photo' Postcards

Stamp Boxes

'Real Photo' Post Cards

Stamp boxes are the small rectangular boxes printed on the back of some postcards, where the stamp is to be stuck.

On 'real photo' post cards, codes in the stamp boxes can be helpful in dating the card.  'Real Photo' postcards are cards that have been  produced in the darkroom on photographic paper.

AZO Stamp Boxes

One of the popular photographic papers used for printing postcards was Kodak Professional AZO Paper

This was suitable for making contact prints, rather than enlargements for which the source of light would be much weaker.

Postcards produced on AZO paper had  AZO stamp boxes on the back.  The style of these boxes varied over time.

- 1904-1918

Four triangles, pointing up.

- 1918-1930

Two 'up' and two 'down' triangles.

- 1927-1940

Squares in the corners.

With acknowledgement to Judy Wms for passing on the 'AZO' Stamp Box' details from Richard (surname not known).

 Kodak continued to sell Kodak Professional AZO Paper until 2005. 

Further Information

On searching the web, I was surprised just how much information I found on stamp boxes, mainly on sites in the USA.  The Playle's Online Auctions  web site that illustrates almost 300 different stamp boxes, including 12 different styles of the Kodak 'AZO' boxes.
