In the last few decades a small group of finds from the Early Bronze age has been found. They have been interpreted as cult objects or clay ritual altars. The aim of this study is to analyze these finds because of the possibility some of them to be interpreted as clay vehicle models. There is a significant amount of finds from neighboring regions which are well known as clay vehicle models. The only group of finds which can be connected with the mentioned artifacts is the so-called clay models of wheels. They are not discussed in the Bulgarian archaeological literature and they have never been subject of a complete study. This work is the first attempt to supplement and to analyze this group of finds during Early Bronze Age distributed in Upper Thracian valley.
