i wasn't sure I would be able to find an issue in my mess, but I lucked out and found one quickly. I loved browsing these and similar card catalogs at the time, always wishing I could drop something crazy (like $20) on stuff, but maybe lucky to spend $5!
Here is an add for the postcard set in 1979 at 132 cards. You'll notice they don't say postcard size, but I am pretty sure that they didn't make that many of the smaller version cards. I vaguely remember now ordering them and being disappointed that they were so big when I got them, but grew to appreciate them.
How about those Laughlin set prices too!!
