ROYAL Mail will tomorrow launch the last in its British Farm Animals Post & Go series of stamps.

The series ends with six breeds of cattle found in the British Isles, illustrated by Robert Gillmor.

Information about the breeds is printed on the back, written by Jack Byard, author of Know Your Cows. This series follows one on sheep in February and one on pigs in April.

The stamps will be available in 146 Post Office branches throughout the country and copies, mounted on a card, can be ordered through at a cost of £3.60 including VAT.

The cattle featured are Aberdeen Angus, Welsh Black, Irish Moiled, Highland, White Park and the increasingly common Red Poll.

Post & Go terminals allow customers to weigh their letters and packets and pay for and print postage stamps and labels without visiting the counter.
