A forger who made more than £120,000 from the sale of two fake paintings has been jailed for two years.
Thwaites was described as a talented artist
Robert Thwaites tricked Antiques Roadshow art expert Rupert Maas into paying £20,000 for one of his copies.
London gallery owner Maas sold on The Miser purported to be by John Anster Fitzgerald for a 300% mark-up, Middlesex Guildhall Crown Court heard.
Thwaites, from Leek, Staffs, made more than £100,000 from another Fitzgerald fake called Going To The Masked Ball.
He was arrested with his brother, Brian Thwaites, 50, after a suspicious client refused to buy a third work entitled Poppy with Imps and Fairies and Foliage .
Robert Thwaites, described as a talented artist despite receiving no formal training, worked as a graphic designer until he was forced to give it up as his eyesight deteriorated.
A book called The Art Forgers Handbook as well as a number of genuine Victorian newspapers used for backing the paintings were recovered at the homes of Thwaites and his brother.
Recorder Terence Coghlan QC told Thwaites: "You are a man of remarkably talented painting skills."
Referring to the paintings, he said: "They are deeply impressive and they have convinced and fooled experts."
Stuart Denny, defending Robert Thwaites, said his client hatched the plan not as a means of funding a lavish lifestyle but in order to make ends meet.
Thwaites pleaded guilty to two counts of obtaining money by deception between April 1999 and February 2004 and one charge of conspiracy to obtain money by deception.
His brother, Brian Thwaites, was given a 12-month sentence, suspended for two years, after admitting one count of conspiracy to obtain money by deception.
Accomplice Gordon Strong, 58, from Bristol, was handed a community service sentence after pleading guilty to perverting the course of justice.
