As part of The Leonardo's new exhibition, "Fantastic Fabrications: Marvels from an Invented Past," Paul Guinan and Anina Bennett will be at the museum Saturday, May 5, to sign books and discuss their whimsical science-fiction illustrations.

The husband-and-wife team's book, "Boilerplate: History's Mechanical Marvel," chronicles the adventures of a steampunk-inspired robot and his role in actual historical events. Boilerplate is only a part of three-part exhibit opening this weekend at The Leo that will included a hands-on tinkering studio that will allow visitors to try their hand at creative invention.

The Leo hours on Saturday are 11 a.m.-7 p.m.

In June, Guinan and Bennett will return for a residency in the Leo's studio lab program to share their talents and vision with visitors.
