Ethnological heritage and philately are the field within which the author of the article defines his framework for discussing the use of motifs from the cultural heritage on Slovene stamps. The analysis is limited to two "ethnological" series issued by the National Post Office: Europe in miniature and Folklore. The greater part of the article is dedicated to an analysis of the Shrovetide mask and masquerading heritage, focusing on the latest issues of the National Post Office and issues of the Ptuj Philatelic Society covering several decades. The author suggests that philately deserves serious ethnological interest.
