Lisa steps into Allen Machielson's "Whoseum" and is transported through time and space to view an impressive collection of Dr. Who memorabilia. From custom-built replicas of the TARDIS and TARDIS consoles to prototype toys, Allen's beautifully displayed collection captures the growth of his passion for the longest-running sci-fi series. Allen's companion, his wife, Chrissy, has developed an appreciation for Dr. Who over the years, but her appreciation may grow when she hears our expert's appraisal. Movie props and costume expert Mark Short began his own collection of screen-used props and costumes with Dr. Who memorabilia, so he's primed with a perfect trade item to entice our collector.
