He saw this in a local shopping centre. "It was located on the "underground" floor of a shopping complex in Kwai Fong, Hong Kong". I spose being underground means they thought they had license to use the roundel.
From Hong Kong to Mexico - Julio spotted this from a local electrical supplies store which used the roundel in Tijuana.
Over to Sydney, Erk Pod spotted the roundel in a Westfield shopping centre
Apparently the children's shop didn't have a railway theme, so not sure why the roundel logo was appropriate.
The final one isn't a current roundel spot, but I like that someone somewhere thought it was once a good idea to make a shirt and a pair of culottes or Twiggy trousers covered in roundels.
Thanks to I.P for sending this one through. If anyone can speak Russian you'll find out its origin. It was taken by Norman Parkinson.
Thanks to all who sent them in. The set of Roundels not on the Underground is here and please feel free to mail me any you spot on your travels, and I'll try to get round to blogging the next ones sooner.
