GRAPHIC designers have made a bit of a boob over the advertising for the Steam museum's next big event.

The Great Western Lego Train Show is hailed as a "must see event for children of all ages."

But it's rather questionable whether parents will want their children seeing one of the Lego layouts it is pushing.

A picture printed in the corner of more than 100 posters and some 20,000 flyers promoting the October 7 show clearly shows a street scene featuring saucy lingerie store Ann Summers and a caf - a typical high street scene in any Legotown.

But in between the two stores at number 69 is a Peep Show with a pair of protruding Lego breasts hanging over the front door.

Although the picture is small, the sign on the miniature building can be clearly seen surrounded by lights reminiscent of a Lego red light district.

Now the Steam museum has taken steps to remove the offending items even though thousands of them are now in circulation having been handed out at the recent Great Western Steam Fair a fortnight ago, which attracted thousands of extra visitors.

Swindon Council said it is unclear where the picture came from but may have been supplied by Lego building groups who will be exhibiting at the show.

It's also not known whether the brick-built diorama will be on display.

Bishop of Swindon, the Rt Rev Dr Lee Rayfield said: "I am pleased that Steam recognised how inappropriate the display was and responded so swiftly to correct their error of judgment.

"I hope this incident might help us all ask more questions about the images our children are regularly confronted with.

"It seems to me that some of the images adults now take for granted could be having a greater impact upon young minds than we care to admit."

One man who noticed the posters was amused but shocked at the error.

He said: "It's incredible that an error like this hadn't been spotted, loads of them must have gone out. But this is supposed to be a children's event and you'd think they would check publicity for errors like this."

A council spokesman said: "The picture in question is very small on the publicity material and it was some time before it was noticed.

"We have had five calls from the public pointing it out, more in amusement than anything else, but we felt that we ought to withdraw the remaining flyers just in case someone was offended."
