Does the label not say Abbas and not Kabbas? Abbas is a male name in Iran, and there seem to be a few Kasraians, but not that many. Possibly could be part of this family, but Wiki talks about three daughters, so one can't be Abbas.
A graduate in law from Tehran University, Nasrollah Kasraian has been engaged in photography since 1966. The Kasraian family is an influential Iranian family. Many of the family members are important artists in Iran and are also internationally known. Nasrollah Kasraian is married to Ziba Arshi, a sociologist who accompanies him on his expeditions and collaborates with him in the publication of his works
