These would be considered in the "Errors & Freaks" category, I believe.
I have some that are inked inside and some that are albino also.
I also have some that are half-inked and some that are over-inked.
The United Postal Stationary Society US catalog might mention these. I will look for my catalog.
Thank you for the replys
Envelopes with colorless indicia from sheet fed presses are called albinos, and typically are valued in the single digit range.
If it is from a web fed press, then it is called a missing color (or color omitted) error and typically are valued in the three digit range.
The reversed image on the inside is called "offset". You get those when an envelope blank fails to move through the press and the ink is instead smeared on the platen. The next guy though then gets the offset image on his backside.
Nice EFOs.
Thank you for the reply. Always learning new and fun stuff.

I have one that has been stamped without ink and one looks like U91 reversed inked on inside of the envelope with reversed (After … days return to). I need some more info on them. Thank you Richard
