Just googled and found people have uploaded images of various past Sears catalog "Wish Books". Here is the 1980 version. Cool.
Interesting!
Here's a TV from that catalog:
That $669.95 would cost about $1778 today -about the same as a reasonably nice 50" HDTV. Of course, this Sears model would've been considered a very good TV as well back in 1980.
