This is a study of the Fourth Air Mail Issue, valid from 18.10.23 to 2.11.23, at the height of the inflation period.  There are only four stamps in this brief period. The air mail service during the time that these four stamps were valid was in operation for only four days. Therefore, flown covers bearing these stamps are scarce.
The 4 air mail stamps were issued on October 18, 1923.In this issue you will learn details about them.
