"From Homo antecessor to Homo exnovo", by Eudald Carbonell
Eudald Carbonell, President of Expominer, briefly reviewed some of the major revolutions that have had a profound effect on us, in this order: the Neolithic revolution, the industrial revolution and the scientific-technological revolution.
Also he talked about the appearance of a new species: Homo exnovo.
Expominer invited participants for this year's edition of its traditional drawing contest, open to pupils aged under 14 at any school in Catalonia.
With the cooperation of Barcelona University's Faculty of Geology, this will be a place to awaken vocations among young enthusiasts who want to learn more about the world we live in.

With the collaboration of the Grup Mineralògic Català.
"Spain's first stamp"
Do you know when Spain's first stamp was issued? And what the postmarks looked like at that time? And how much one of these historic stamps could be worth? The answers to these and other interesting questions at one of the largest collections on this subject in Expominer.
"Postal history of Catalonia"
From pre-philatelic letters prior to the 18th century (before the appearance and use of stamps) to original bills of exchange. The exhibition included historic items about the Civil War and the Republican exile.
"The Republican exile"
Letters to prisoners at concentration camps. Cards and photographs that never reached their intended recipients, because they were censored or the addressee had died.
