This is a postcard advertising Kainit and Potash Manures, with details on the front of the ‘Oat Experiment’, held in Yorkshire in 1903.   The caption and the notices in the illustration claim to show the additional yield and profit that can be earned by using such manures, compared to alternative manure or none.  The card was posted by the advertiser in 1905.

The postcard is in fair condition with some wear to the corners and edges, and some marks on the back.    There is a crease at the top right corner.
