Effective Advertising

I found the advertisment for John Deere lawnmowers in a magazine very effective.
The background was a lush, green lawn which had been blurred the further one was to look so that the focus was on the green and yellow mower itself.  The font was either green on a yellow background or yellow on a green background which I believe keeps in pace with those who are dedicated to the products history and the fact that those colors alone symbolize John Deere.

An ineffective add was for credit cards in a magazine. The back ground was a simple grey and the card was the only thing with color on it. The font was not large enough to really draw someone to read it.  I think I am just sick of credit cards any way and this add made me think of how people only focus on the credit card and not what it does to them if out of hand.
