Is there a way to differentiate joint issues released at the same date but with different designs from stamps released at different dates but with the same design ?
It is always possible to do this differentiation. It was proposed to give the name “concerted joint issues” to stamps with the same design (which may happen accidently) issued at different dates and the name “parallel joint issues” to stamps issued at the same date but with different designs. However, we have to take care about “accidental” same design, i.e. same design used because taken from a common original reference (i.e. only one portrait of Cristofer Colombus is existing). Therefore this distinction is not used to avoid too complicated subdivisions.
