The collection was born from a national event/project called Octoberskine 2021 organized by Moleskine Mexico, in which Mexican artists are invited to create 31 drawings during the 31 days of October, each day with a different theme. For this edition, the drawings are inspired by the animated series The Simpsons.

​

The collection is completed with 7 US dollars of one dollar, with the characters of the series as the main image of the bill.
