The names "Silver Age", "Golden Age" and "Current" refer to the size of comic book the boards are made to back. The very old comics (from the "Golden Age" of comics) are the biggest. The new comics today ("current" ) are much narrower. The "Silver Age" was a time in between, when the width of the comics was in between Golden and Current. You can wind fabric on any of them-- they are all the same length, just different widths.
These are perfect for 42" wide fabrics. You fold them in half, lengthwise, like they come on the bolt, and then fold that in half again, so they end up half as wide. That is just about the same measurement as the longest side of the boards, so you can wind your fabric around them and they fit just perfectly. It's a cool idea!
