Claudius II versus Quintillus

[Victor]

I made the picture below for someone on another forum; but figured I would post it here also.

Claudius II and Quintillus were brothers and bear a striking resemblance to each other. However, even if you can't make out the legend on one of their coins, you can easily differentiate between the two by their hair. Claudius has straight hair and Quintillus has curly hair.
