Corbett found no copies of the 1R from 50-1865 in his large survey from 1983-1992. However, Bash showed a cover with a pair of these stamps in Mexicana January 1985 which is NOT the same as the one shown here! It's quite amazing that these two covers were somehow missed.
Corbett found one unused, one used and two covers with the 2R stamp. One of those covers is the one shown on this site.
Please send a kind thought to the owner(s) of these covers, since his / her / their generosity has allowed you to ever see them!
