Abstract. The state of the art in the current research on the final stages of Open Star Clusters dynamical evolution is presented. The focus will be on observational studies and their achievements. By combining together photometric, spectroscopic and astrometric material, a new look at this exciting topic is now possible, thus providing a solid observational foundation for a new generation of theoretical studies on the subject.
