I don't know if those were only offered that year, but there was a pair on eBay a few weeks ago. Pictures are in the Ode to the Albert Slippers thread. I also recall a pair of those duck embroidered khakis on eBay, but I'm not sure if it was the same pattern or just a similar one.the velvet slippers later down.
Like many hereabouts, I was there then. I used to find those old catalogs so annoying. You couldn't really tell what anything looked like. It was all sort of an "artists conception", although from today's perspective I appreciate the images, in a nostalgic sort of way.
