What better way for an artist to produce a self portrait than to show himself at work? An innovative self portrait by the Irish artist Thomas Ryan, a past president of the Royal Hibernian Academy, comes up at the next sale by R.J. Keighery in Waterford on June 13. The artist, who was born in 1929, is probably more associated in the pubic mind with still life, flower studies and landscape than with nude models but this is how he chose to portray himself. It is one of two works by the artist at Keighery’s. Liffey Up Stream is estimated at 5,000-7,000 and Self-Portrait is estimated at 4,000-6,000.
