(pcp-wm) The WWF (World Wide Fund for Nature) is concerned for a long time with the protection of species worldwide, which becomes an increasingly urgent concern when you see how many species are on the verge of extinction.

Special editions with the WWF logo are published in numerous countries. These are included in the new catalogue, which was published in its 2nd edition on 20 December 1919. The paperback catalogue contains about 2,900 colour illustrations and about 9,000 price quotations on 168 pages. It is available for 49.90 euros. ISBN 978-3-95402-289-4

With the first edition of the motif catalogue “Dinosaurs – Whole World”, which was published at the same time, MICHEL is covering another popular area of thematic collecting. It contains not only stamps depicting dinosaurs, but also species of animals that have long since become extinct (e.g. mammoth, sabre-toothed tiger, etc.). 160 pages present about 1,600 colour illustrations and about 12,000 price quotations. The paperback catalogue is available for 69.90 Euros. ISBN 978-3-95402-299-1
