I don't know if it was a competition or not but I don't recall my local Beatties running any competitions for the Flaggslight_overbomber wrote: I know my local Beaties toy shop in Kingston (Surrey) had a USS Flagg on display in the window in late 1987 as part of a competition where you could win that particular USS Flagg if you correctly identified the figures that they had displayed within it (Maybe somebody out there still has the flyer that went with this?). Perhaps Hamleys ran a similar competition?

The guy that told me the story seemed to recall that the Flagg might of been onsale at that point in Hamleys and his Dad really wanted it (whether or not it was for his son or himself I don't know) and was on the edge of trying to buy it but the plan was dampered by his mum dragging them both out of the store.
I am quite tempted to send them an email to see if they have any records of the display or not.
