That's me out.

Third picture is The Netherlands, Dutch Lion with arrows in his paw.

Your Mexico Revenue is one of a VAST amount of revenues.
A discipline too deep for me,
The revenue catalogue, is a King's ransom.
however I have it as a "Special Customs" undated.

The middle image with three stamps in a vertical format are Russian revenues. Right below that, in the image with two stamps, a rose stamp marked 1888 and a yellow stamp, those are revenues from Greece and Romania, respectively.

You won't be surprised to hear that the Greek stamp is from a series issued in 1888. Forbin has the Romanian example as the second lowest face value in a five-stamp set from 1872.
