Our vacation to Vermont included a trip to the Shelburne Museum. There was a quilt exhibit. Most of the quilts were from 1850 - early 1900s. They were hanging behind glass in large swinging doors. Because of the limited space, I wasn't able to get a straight on photograph of many of them and the glass caused some distortion and glare. However, they are not bad.
Look at the quilts with the cut-outs for a four poster bed.
