If you collect vintage Halloween decorations, there's always a lot to choose from at the Brimfield Antiques Show (where I visited last week for a few days). But, let me tell you, this stuff doesn't come cheap.
I overheard a dealer saying that prices had gone down a bit about six years ago, but now are back as strong as ever. I love looking, but I hardly ever buy. Even the stuff from the '60s and '70s can be expensive. The prices on early decorations can be in the $100s.
Many of the older decorations were made of paper and tons of them got ruined or tossed, leaving fewer behind. So... scoop up whatever you see if you're out at yard sales or estate sales.
Some booths were decked out for autumn. I loved the display by Log Cabin Country Primitives.
They did a great job pairing mums and pumpkins with the items they were selling. See how they used the long box as a table centerpiece? You could do that, maybe with an old toolbox.
