A superb and neat circle of specimens. Produced for W.Watson & Sons between 1882-1908.
'Exhibition' slides of this type show off the prowess of the mounter. The general opinion is that they are of little scientific value, however they are a testament to the patience and skill of the individuals who laboured to produce them.
Always desirable slides to have in any collection and much sought after.
Price includes shipping.
