Here are a few more ideas that I quickly mocked up in photoshop:
using an existing MOS poster I created this one. I used the same information again to see the layout and to see how the colours worked. I think that this idea worked quite well and I really like the typography going on in the bottom left corner and the logo on the top left.
I wanted to create a very simple design to see how it looks, after creating this I don’t think it looks very professional and I think that it looks too simple, plain and boring. I would NOT want to be attending this event!
