Gooding #24F4. A very crude forgery. Most of the stalked pearls in the side frames touch the inner or outer curved lines of the frame. The zigzag lines inside the side frames with curved ends instead of pointed ends. There star ornaments at the stamp corners are poorly drawn and do not have shading lines. 

The eyelid of Isabella is just a straight line. The lock of hair and ribbon of different form. The inside oval frame around Isabella's head is missing. On the genuine stamp the neck of Isabella has an almost pointed left end. On the forgery it is at a 55 degree angle.

All the letters are thinner. There are no stops before "CORREOS" and after "CENT". The stop between "25" and "CENTS" is a comma.
