Looking for Gift Ideas for a Commercial Building Purchase
My clients just purchased a building with me and they will be ending the long-term lease on their current location. 

I wanted to get a gift to symbolize and remember their old building. I've seen small plaques with a photo of the building with the address and years they were there, but it feels a little bland.

My clients run a business that's mostly online-based, but I was hoping to be able to have something memorable for them to look at that might remind them of the good times.

I'm happy to outsource anything to have it created, I have a month timeline for this.

Thanks for your suggestions!
