The easier of the two Anonymous-backed groupings in the Broadleaf class cards, and though it trails the Broadleaf back by some distance in terms of availability, the factory 3 backed cards (A3) are a relatively completeable subset within T207 as a whole, though primarily at lower grades. 

A3's can often be found with slight color variations in the printing on the back. Where the A25 backs are often seen with dark black printing, the A3's are usually not so pronounced, and are often found with more muted black printing, sometimes with tones tending towards brown or even purple. Some cards have been seen that show clear tonal variations of brown to purple, suggesting a liquid agent may have been involved.
