craftgrrl | I don't even know what this is called...

My friend just moved to Toronto, and i wanted to send him some pictures. I only have a couple but I wanted to make a small collage, and then do a frame with maybe some maps of winnipeg and toronto applied to it and maybe a couple of pictures of Winnipeg landmarks (our city) or something. I am not exactly sure how to do this, and what the best type of frame to use is. I have done it once before with okie results, but I want this to look really good. Does anyone have any tips or even know what I am talking about?

Thanks in advance!
