other macmillan coffee morning posters

a lot of the posters used for macmillan coffee mornings use the three macmillan colours: green, purple and white. I think these represent the charity really well and make it obvious that it is in association with them. As 10 associates bake off competition isn't trying to appeal to the general public it doesn't necessarily need to be so obvious that it is for charity as people will already know this.
