I have 2 comic spinner racks in my comic room.  They're not vintage.  I bought them new a few years ago.  I think the company went out of business though as I Googled them last year but couldn't find them.

Here's one of the racks.  It's not the best picture but you can kinda see I keep my Sin City collection there, as well as Tomine's Optic Nerve (which is the best "slice-of-life" series IMHO).

I hang action figures on the racks, including this Gwen Stacy.  I got John Romita to sign it years ago at a MegaCon.

Here's the 2nd spinner.  In this rack I have the complete Strangers in Paradise series, along with Astro City, Marvels, Planetary and Miller's DD run.

I have a third comic rack, but it's not a spinner.  It's the kind you attach to a wall.  I like it because the bins are wider so I can store Silver Age books there.  Here are a couple of pictures.  Thanks for reading.
