Hello
I have just joined this forum in the hopes of finding a source of binders as the one I had as a child. It was a faux leather with an internal spring steel "C" cross-sectioned piece that ran the length of the spine but covered as not to be visible. To open the binder and remove the pages, one simply folded the covers backwards. This opened the clamp to remove or add more pages. I believe it was originally given to me as a stamp album but I've not found any in those sources.
Thanks
