Royal Mail Set of 6 Stamps

The Royal Mail have announced that in April 2018, they plan to produce the set of stamps, on the subject of 're-introduced species' which they commissioned Tanya Achilleos Lock to paint.

'Many species have become extinct in the UK. Reintroduced Species in April marks the successful reintroductions that conservationists have made to begin to re-establish six once common species of plants and animals'
