Istonio Marina (province Chieti) was a small camp with a capacity of up to 185 internees. It was primarily intended for Italian political prisoners, but it is known that some other internees were there too. Postal items are very rare, especially those sent abroad...
30 cent stationery sent from concentration camp Istonio Marina (11.8.43) to Split. The sender was transferred from the concentration camp Tortoreto (see here).
