Incredible 1959 hawaii scrapbook

Hi folks. I am a new member to the forum and joined so I could research and find enthusiasts of vintage hawaiian stuff. A dear friend has us helping him sell his late mothers estate and we found this incredible scrapbook done in 1959 of his grandparents fabulous hawaii trip. The book itself is an incredible black enameled box/book that has an integral storage area and a wind up music box. It was meticulously put together with fabulous pictures, postcards, menus, coasters, swizzle sticks, itineraries, etc.
Our friend has no interest in keeping it, but I would assume it is very collectible. Does anyone around here know where to find collectors of this kind of thing??
Thank you so much for any advice or help. Our hope is to find a buyer who would appreciate it's value.

Hi. I'm sure we'd all like to see a picture of what you've got.

I will take some photos tonight and post them (hopefully, I can figure out how to upload them)
