Be kind. My mother painted it years ago.
The Sheltie looks like my dog. Even has one ear up and the other slightly bent.
I suppose if we're talking about decorations, I can't include the weird stuff that just happens to be sitting in view. I've got two different electronic projects going on in front of the TV, with two tables full of tools and parts.
As for things that are meant to be seen, there are the full-sized, plaqued posters for Star Wars, Raiders of the Lost Ark and Gone with the Wind, and the matted and framed black-and-white movie stills of Jimmy Stewart, Don Knotts (as the Love God), and Sean Connery and Donald Sutherland (both in top hats and mutton chops).
I've got a large framed set of 16mm film reels in various sizes, wound with an actual copy of "I Am Joe's Spine," a school film narrated by Burgess Meredith (wish I could play it). The reels are in a deep, glass-covered frame, on a background of red velvet, with a replica film slate and assorted b-movie stills mounted in an oversized strip of film made of black cardboard. Made it myself a few years ago. It's about the same height and width as the movie posters.
There is, of course, also the full-sized arcade machine in the dining room, with a full-sized dalek stenciled on one side, and the Doctor Who diamond logo on the other. Another one of my projects.
I've got copies of three computer ads from magazines in the early 80s, reduced and framed together. Shatner endorsing the Commodore VIC-20, Bill Cosby for Texas Instruments, and Isaac Asimov for the TRS-80.
I've reprinted and framed a few of my more interesting news photos. Firemen silhouetted against a burning barn, framed with a shot of Mennonites rebuilding it the following week. A thoroughly demolished minivan on the highway, with police and firemen in the foreground, and an air ambulance lifting off behind it. Three shots of a funnel cloud forming behind spectators at a tractor pull.
And we have an entire magnetic blackboard wall in the kitchen.
