A total of 644 lots went under the hammer in the auction. A collection of hats from the costume department were laid out in front of him as he checked the catalogue.
The auction was the final act of the liquidation drama which brought about the theatre's closure in February 1980.
Mr Sidebotham, who worked for Wolverhampton estate agents Walker, Barnett and Hill, was pictured at the preview sale in July of that year.
As well as props and costumes, much of the theatre's furniture and fittings were also auctioned. He was sitting at one of the most valuable lots – the managing director's desk which was a 19th century copy of an 18th century original.
After the sale, workmen moved in to start an extensive renovation of the theatre, its second in a decade, prior to its eventual re-opening by Wolverhampton Council in 1983.
Seating in the upper circle was redesigned, creating an overall capacity of 1,200, while the existing seats were stripped and rebuilt. An induction loop was installed for the hard of hearing and ventilation systems renewed. Work was also carried out in the dress circle and foyer.
