Two paintings worth about £1,000 each have been stolen from an art gallery.
Kent Police said a man fled the Francis Iles art gallery in Rochester with the artwork after being confronted by staff at about 1300 BST on 17 August.
The two paintings were of steam trains and would appeal to railway enthusiasts, they added.
The suspect was described as being in his mid-to-late 50s, with long grey hair tied back in a ponytail, and he was wearing a black trilby-style hat.
He was about 5ft 8in tall, of medium build and also wore a black three-quarter length leather jacket, over a white t-shirt and black trousers.
Det Con Amanda Neimer said: "The paintings belonged to the artist, who is obviously very keen to get them back into her possession.
"It was a busy time of the day in Rochester so we believe someone must have seen this man leaving the shop after the paintings were stolen."
