To expand and compare:
I have made scans of a color proof of the 2c in red, from Spain, as well as a genuine copy of the 1/4R from Cuba. They both used the same basic design and just altered the denomination portion to reflect the country monetary system
Note the circled areas. On yours, the left hand ribbon, with the shading in it has a distinct upward curve, which is prevalent in all 4 examples.
On my scan, that same area of the ribbon is basically flat.
On yours, the first C of CORREOS has the ends turned upward on the bottom, and downward on the upper arm.
On mine, the arms of the C point straight out, and look more like a U turned on it's side.
Start comparing other details and you will quickly see differences. The genuine ones are very crisp, whereas the forgeries are pretty crude.
