Efo: Misperforated Mexican Revenue W/ Monterey Overprint

Hi all, been lurking for a few years and this is my first post. A big thanks is due to all the folks who share their knowledge in these forums, I've learned a lot—thanks!

I've been reading everything I can find on EFO, is this stamp (hopefully uploaded) just a freak no one (except me) would be interested in?

Also, am I correct that the misperforated stamps would have been an entire sheet? How many stamps would have been on the sheet?

Finally, I can't find an image that matches this stamp, but I probably won't buy the catalog for the mexican revenues, so if anyone can ID, that would be great!



Thanks!

Documentos y Libros, the 1904-1905 series, the second of 12 values. It's shifted, for sure. I have quite a few Mexican revenues and none are off to this degree, but it isn't shocking - I have many postage stamps that are shifted more than this.

Thank you for the information!
