Technique and condition
This painting is executed in pencil, watercolour and gouache on a blue/grey coloured, wove paper. No watermark is visible. On the recto the pencil outline has been filled in with thin washes of watercolour. Highlights were then added in white and yellow gouache. On the verso a quick pencil sketch has been drawn and then white gouache highlights have been added to indicate the buildings and the foreground. There is some flaking of the white gouache on the recto in areas of heavy application.
There is a patch of black smudging at the top of the centre of the image. A brownish stain is visible in the bottom left-hand quarter of the verso and a small brown stain in the bottom right-hand quarter of the recto, to the left of the Turner Bequest stamp.
Prior to conservation there was some cockling, especially along the top edge of the sheet where it was attached to an inlay paper. All four corner of the verso are skinned and it is evident that they have previously been attached to another backing.
