Briscoe Bison Society Presents the Fifth Annual Collectors Summit

Headin’ In or Headin’ Out?
The Western Art Market in 2023

Headin’ In – Summit Session I

The first session will explore the changing nature of the Western art market as it relates to long-time collectors who perhaps are reaching their zenith. How has the art market changed over the years? As collectors begin “headin’ in” from their journey, what should they expect as they begin to transfer or sell their collections? Moderator Michael Clawson and panelists Abigail Kampmann, Tim Newton and Don Oelze will explore the changing nature of the Western art market as it relates to long-time collectors who are perhaps reaching their zenith.

Headin’ Out – Summit Session II

An art collection is an intentional accumulation of works centered around a theme. Finding a focus of a collection is seldom a rational decision. At first, collectors simply buy whatever they like, without giving much thought to it. This is a great way to explore their tastes and interests, but after a while, a pattern begins to emerge. This session will explore the journey of “headin’ out” as novice buyers of Western art begin making the transition from buyers to collectors. Moderator Michael Clawson discusses with panelists Mary Ross Buchholz, Robert Oliver and Beau Alexander.
