Alec Thibodeau's "Good Librations" is an edition of 500 lunar calendars detailing the 366 phases of the moon for 2008. The calendar is based on the skies of Providence, Rhode Island but will function accurately anywhere in the Eastern Time Zone and to within a day of accuracy for any location in the Northern Hemisphere. Special illustrations represent New Moon, First Quarter Moon, Full Moon and Third Quarter Moon for each four week cycle. Clouds serve as placeholders in months with fewer than 31 days.
The letterpress print was produced on a Cloud Nine Classic Laid paper by Dan Wood of DWRI Letterpress. It is printed in blue, and metallic white/silver and white inks. The edition number has been debossed into the print in a 14 pt. Bernhard Gothic Medium Condensed.
