I was looking for inspiration in Google.
I tried to implement these ideas to my future design.

I like the idea of Milton Glaser, composition is centred, the mix of fonts is interesting.
I like the mix of colours. Two of accent colour and black and white. The composition is very clear and balanced.
This tourist guide is really interesting, with a lot of images, but it is too much details. I would use the idea of the photo and 3 circles in the middle.
In my next post I will show the first prototypes of my banners.
