David Beckham, Samantha Cameron and Amy Winehouse all have at least one thing in common aside from their fame - a tattoo.

In the past, tattoos were (main) a badge of belonging to a group and it was (general) tribes, military personnel and lorry (drive) who used them. But they are now used to express individuality and can range from the small dolphin on the ankle to huge drawings of a fan's (favour) pop group, or even designs covering most of the body.

On 7 October, the Dana Centre at London's Science Museum is putting tattoo culture under the microscope. Katie Maggs, associate curator at the Science Museum, said there would be a (collect) of late 19th century tattoos on display, together with the (equip) used to make them.

“We are displaying a (surprise) variety of images. There are lots of beautifully designed women, military ranks, and there is also a pig on a bike,” she said.

The event will look at how tattoo use has changed and examine whether (improve) technology may mean that tattoos do not need to be a permanent (decorate).

Dr Raj Mallipeddi, a well-known dermatological surgeon in London, said while he would not advise against tattoos, he would always recommend (care).

“There are different types of potential problems following tattooing; for example, allergic (react) to the ink, which may lead to a form of eczema or red spots on the skin.”
