It may not be the grandest bird study by Archibald Thorburn, but auction price may be quite modest

                                                             

Original studies by Archibald  Thorburn (1860-1935) typically cost four-figure sums when they come up for auction. Featuring a Woodpigeon and a Turtle Dove,  a pencil sketch attributed  to the great Scottish artist  is expected to achieve a more modest sale price - between £200 and £300 - when it goes under the hammer at a sale to be conducted on Saturday January 10 by Tennants of Leyburn, North Yorkshire. Also included in Lot 15 is a pencil study, also attributed to Thorburn, of ivy on old timber.
