In my view, they're just local/county revenues. I won't put them on my cinderellas albums. But, Mike, knowns a lot more than me!
You are too kind Cursus, but I am sure that isn't true ! If I had as much knowledge about my chosen field as you do about yours, I would be very happy. But that isn't going to happen any time soon.
Barcelona and Catalonia Cinderellas will be No.1 here for a long time to come, and that is largely down to you and your expertise.
Which brings me to the leading question.....do you collect Revenues from your area ? I do occasionally collect Revenues but have separate albums for them like I do for all types of Cinderellas.
Revenues will always fall under the Cinderella Umbrella. At the recent World Cinderella Stamp Congress, one session was taken up with invited Revenue displays and a talk by the Revenue Society of Great Britain.
