Hi all, I recently wrote an article about a Gen II distribution event that happened in Mexico where Mew and Celebi were given away. I assisted to that event and still have a Celebi from it, so if you have any questions, feel free to ask, below is the link to the article:

There are two other Mexican events of Gen I that have not been documented yet, I'll write an article about them eventually.
