I have seen this on another site and in my view deserves to be better known.

"" A Better Welcome to Forest Hill ""

The proposed mural design features the walrus mascot of the Horniman Musuem. Apparently Lionel, the artist, will tweak the yellow colour (shown in the mock-up) to a London Overground orange.

The site for this mural will be under the railway bridge on the South Circular.

I have no connection with the organisers or the other website but am simply spreading the news.
