World 1830/2000 - Great collection of world stamps

Good time of the day. I present to your attention the largest collection of postage stamps in Italy. The collection includes 160 books, 160 coverts and a separate package, weighing 700 grams with mixed postage stamps dating from 1830-2000.
The collection is very extensive, the creation of these books took 40 years of the life of two Italian collectors from the city of Ancona. They meticulously sorted the stamps by year of manufacture, place of manufacture and quality. On the first pages of each book, you can see the best examples of stamps from the series. Almost every book has a front page with rare and old stamps from the 1830s and above. Some of the books are not fully filled, which gives you the opportunity to continue building your collection.
In this lot, you can find such compilations as: Poland, Russia, Svizzerland, Italy, Ancient States of Italy, Vatican, San Marino, Svezzia, Germani, France, England, USA, Romania, Czechoslovakia, Regno Italia, Israel, Dubai, Japan, Indonesia, India, Mongolia, Brazil, Colonies of Britain, France, America and many other countries.
This lot contains a huge number of ready-made sets, rare postage stamps with a limited edition, so by buying this collection, you invest in something that will definitely bring 5-10 times more than what you will pay for it, because the market of postage stamps has always been alive and they do not lose their price.
The approximate number of postage stamps in this lot is 115,000 units. Most of them are from 1830 to 1950. Inside you will find a whole world of history, famous personalities and their exploits. Buying the largest collection in Italy, you become one of those who will be almost impossible to bypass in collecting!
I repeat. Not all books are filled to the end. Not all pages are 100% complete and not all stamps are in identical condition. The entire collection is in excellent condition, especially considering the year of its creation.
As a gift to the collection, you will also receive a collection of different postal envelopes with stamps, unique in their kind. More than 500 envelopes will be included in your order as a bonus.
