John Everett Millais - Bubbles (1886) and Pears Soap advertisement
Picking up on the fine line between Fine art and Advertisement point, this is an example that was presented to us. On the left we have the original painting called Bubbles by John Everett and Millais in 1886 and on the right we have the same image, but "Pears Soap" has been added to it to advertise the product. Now the images are exactly the same but the only difference is the text, and this has completely changed the purpose of piece, so we could argue that there definitely is a fine line between the two subjects.
Other than that I don't really know what else there is for me to say, other than graphic design is a good way of mass communicating as we are all exposed to art everyday in some form or another, and it's rather easy to get work out there, especially that we now have the internet.
