Speculation on stamps dedicated to famine
There is a series called "Odesa issue of famine relief". It dates from 1919-1922 and consists of 7 different stamps. The series is classified as non-postal, and the stamps were never put into circulation. They were printed and released for sale by the Association of Italian Philately (Venice). There is no information about the customer, distribution options, or the results of the proceeds from their sale in favor of hunger relief.
It is difficult to say whether they are a fake or just an artistic fantasy. There is also a story that they were made by an Italian businessman, Marco Fontano, to deceive collectors. There is also information that the Pomgol public organization could have been a possible customer.
The colours of your stamps raise questions.
