One Labor Day weekend when everyone in Boston has gone away, the buildings decide that they should take a holiday as well. They travel up to Portland--where ""the new buildings [were] introduced. . .The old State House went to see the Long-fellow House; the museums traded pieces of art [and]. . .The two libraries stood close together and exchanged the latest journals."" This beguilingly imaginative spoof is handsomely illustrated with Priest's scraperboard illustrations (resembling b&w linoleum prints), though his bold designs rather mask the pleasing incongruity of his juxtapositions. A curiosity that should entertain children beyond the picture-book age.
