Ok, I would so totally use a set of these on my bed today. This picture also features one of my favourite things, the use of toys in the child's bedroom set. For some reason, I really like that extra detail, I probably need to get out more. That's the Dinky Toys Enterprise by the way, one of the cooler 70's Star Trek Toys IMO.
Nothing says "1976" more than the Six Million Dollar Man and Evel Knievel, the matching curtains are just too cool. That's an Ideal Evel crash car on the nightstand BTW. I slept in a hammy down bed which you couldn't get kids sheets for, so I had to settle for pillow cases, if you had these, I envy you.
