Anyone remember the trusty Observer Book of British Birds?

No fewer than seven copies of The Observer's Book of Birds were included within a single lot that today went under the hammer at a sale conducted by auction house Tennants at their saleroom in Leyburn, North Yorkshire.

Also within the 370-volume collection were sister titles on heraldry, aircraft, geology, furniture and much else, plus one on birds' eggs.

The hammer came down at £420.
