Hi ladies! I may cross post this in DIY, but I know you and love you ladies.

Our reception's theme is "Golden Age Amusement Parks" and our decor is going to be related to amusement parks of the 1920's and 1930's. I was having a chat with my brother and we came up with the idea of having a display of photos of roller coasters and carousels from currently operating parks that were around back then too. FI loved the idea, and we've decided we're only using coasters we've ridden together.
Here's the question though. Does anyone have ideas for how to display a group of photos as a centerpiece on a round table? I found a really cute "chandalier" idea that I stuck onto my Pinterest but I'd want to do it in reverse so the small layer is on top.
Around the outside of the display I want to lay brass rings (like some vintage carousels still have - catch the brass ring for a free ride) with "Kat + Nick 10-7-12" written on them in black fine-point sharpie that the guests can take home if they want.
Any input? I'd like a classy, not so much cutesy, way to display them. I'm finding several ideas that would look great in a rustic or shabby chic themed reception, but not in more of a 1920's glamour theme.
