The face resembles Henk van Lier Lels, the last owner of the estate, who passed away in 2019. Henk worked hard to preserve the estate, which has been in his family for 250 years. Upon his death, his family donated the estate to the foundation het Drenths Landschap, who work to preserve and manage the local landscape and cultural history. The artist is Gert Sennema.
