From source (23 December 2023):

Get 4K quality for printing! Maximum 105x75cm canvas to get 100% quality!

100% of the profits and donations until December 31 will be used to give food to low-income people in Colombia.

Starting January 1, all profits and donations will be given to UNRWA to help refugees from the war in Gaza

The cost of living in Colombia is very cheap, so a person can eat for a month with 100 dollars a month. At the end of the year, my family plans to give food to homeless people in towns on the Colombian coast, where live the main conglomerate of people displaced by guerrillas and there is rarely water or electricity.
