The left one is a fiscal (tax) stamp, the middle one is from Eritrea (formerly an Italian colony), and the one on the right is hard to read because the picture is so low in resolution. What does it say at the top? -jmh
The one on the right is from Italy, Scott #317.
Indeed it is. Issued in 1934. And the middle one is from 1933.
Thank you both for your assistance. I can't find the left stamp you ID'd as a fiscal or tax stamp in Scott. Are these types of stamps not listed in Scott?
revenue, fiscal, savings and similar stamps, unless also valid for postage, are not listed in Scott.
Thank you, Michael. Much appreciated. Don
