Provenance History
Likely stems from a private collection of early 20th-century Australian Modernism; Stylistically consistent with the artist's experiments at Heide and travels to Central Australia.
Art Historical Significance
Highly significant as a likely early work by Nolan during his most formative period. It bridges his interest in folk art aesthetics with the psychological weight of the Australian interior, predating or coinciding with his famous Ned Kelly series.
Notable Features
The distinctive 'alien' or mask-like face of the rider and the specific purple-pink hue of the mountains (indicative of the Flinders Ranges) are hallmarks of Nolan's 1940s output. The use of Ripolin-style industrial paint is also a possible feature.
Condition Issues
Extensive vertical and horizontal drying cracks (craquelure) throughout the sky and mountains. Signs of surface abrasions and potential pigment flaking in the lower right quadrant. The board appears somewhat unstable due to age.
Conservation Recommendations
Professional structural stabilization of the support; cleaning of surface grime; consolidation of flaking paint layers. Display in a climate-controlled environment with UV-filtered glazing.
