Robin Boyd most likely saw Solstar at Asher Bilu's exhibition at South Yarra Gallery in September 1968. In November 1968, Robin Boyd arranged for the loan of this painting from South Yarra Gallery to Australian Pavilion at Expo '70 in Osaka, where Boyd was appointed Exhibit Architect. It hung in the bedroom over a bed, containing a life-size cut-out figure by Bruce Petty, in the Model House Interior exhibit on modern living in the Space Tube. On its return from Expo, the painting was in transit at the Boyd's home in Walsh Street and they liked it so much that they decided to buy it. Solstar originally hung on the wall at the end of the galley kitchen. The artwork at the Boyd's home in Walsh St has been moved several times over the years. Solstar now hangs above the dining table, but at the time of Solstar's acquisition, the Boyds hung the painting "Winter Triumphant" (1920) by Penleigh Boyd, Robin Boyd’s father, above the dining table. In early 2021, Asher and Luba Bilu visited Walsh St to view Solstar again. Asher was extremely happy with how the painting looked and its condition 53 years after painting it. He requested it be hung a little higher and he returned in April to make some minor restorations to remove scratches. Silver mixed media with large black circular area in the central lower half. On reverse has the title: Solstar/A. Bilu/Arrow showing which way up.
