Graffiti sketches is where most newcomers begin but really you should
 start by asking yourself - graffiti - what does it really mean to you? 
Most people see it as something  that emerged only in modern society, 
scribbled by urban youth on  railway bridges. However, its use can be 
traced back to ancient  civilisations, such as the ancient Egyptians 
whose hieroglyphics could be considered a form of what we know today as 
graffiti. One can even say that graffiti or writing, as it is  more 
commonly known, dates back to the origins of mankind itself,  when 
Neanderthal man's sense of his environment was expressed  through cave 
drawings.
More
 often than not graffiti has been characterised as vandalism  due to its
 associations with the spray-painted drawings you often  see plastered 
over buildings and walls in cities.
Graffiti art can be 
categorised in three common forms: Tags,  Pieces and Labels. All of us 
have walked down a street and seen  various walls covered with graffiti,
 but can we differentiate one  item of graffiti from another? The most 
common and the easiest to  recognise is a tag.
A tag is usually a simple one-coloured design (though it can be  more
 complex). Put simply, it is a depiction of a writer or  artist's 
nickname or message, and its aim is to send a message to  other writers.
A
 piece or masterpiece is a more complex form of graffiti art where  a 
writer usually starts with some kind of pre-conceived plan or  sketch. A
 piece tends to take graffiti art more in the direction of  character 
art, which has a big fanbase. People will often be able  to distinguish a
 writer's work by their character designs alone.  Artists like D*Face, 
Insa, Sickboy and Inkie can all be recognised  by the characters or 
symbols in their pieces.
A label is when a writer's tag or 
character design is printed on  posters or stickers. Labels can be found
 in most cities around the  world. This can be a great way for all kinds
 of artists to promote  their art far and wide; usually tags are quite 
hard to see and they  are only going to draw the attention of people 
interested in street  art. You often see labels plastered on the back of
 street signs,  lampposts, and anywhere with a smooth surface that can 
have  something stuck to it.
Although graffiti art seems to have 
been part of the mainstream for  ages, it was not until the 1970s that 
graffiti reinvented itself  with a more modern term named writing, which
 first took root in the  United States and later spread across the water
 to Europe.
The last decade has seen writing really take hold of 
the global  art scene with celebrities emerging from the hub of graff 
artists  around the world. It is only now that you hear about graffiti  
events like Secret Wars and people like American actress Angelina  Jolie
 forking out £100,000 for an original piece by the notorious  
Bristol-born artist Banksy. Also, a new record was recently set when a 
piece went for a massive £280,000.
Graffiti art is the new cool, 
with hundreds of companies in the last  few years jumping on the street 
art bandwagon. Graffiti is no  longer just a shunned art form, yet it 
still manages to stay
