This is my delima.The color
As you see in Fig#1 Below. The Tail has no dark shading on top.

As you see in Fig#2 Below it clearly has.

Now seen in Fig#3 Below both Stamps Side by Side.

Now on to Fig#4 Below You can see the Spur has a spot behind it. And the Sunset is void of the Darker shade on top.

Now Fig#5 Below. The Sunset clearly has Darker shading on top and a spot in the center. As For the Spur it is void of the spot behind it.

What my Question is. Do I have Myself A very good Piece of rarity. Or was this Common in the 1960s printings of Decaris.
I have been collecting for Two weeks now. I cant seem to put these little Flat pieces of paper down. I am learning so if my Questions are of the Stupid Variety Please forgive me.
Thank You
Steve
