Photographed in 1977, this image depicts a superior view, i.e., viewed from above, two scabs, a chickenpox scab on the left, and smallpox scab on the right, as a demonstration in comparative morphology. See PHIL 3327, and 14761, for other smallpox-chickenpox scab comparisons. Unlike smallpox, chickenpox lesions are superficial, and on any one part of the body, lesions can be found to be in different stages, i.e. papules, vesicles, and crusts. Also, chickenpox rarely has lesions on the palms and soles, which is not the case with smallpox.
