"Kerouac Retrieved" includes personal items retrieved from Beat Generation author and Lowell native Jack Kerouac’s last residence, in St. Petersburg, Fla., and includes the writer’s desk and chair, clothing and personal items and some unexpected things like three rudimentary cat carriers constructed by Kerouac and marked with each favorite feline’s name (Timmy, Pitou and Dobie). The exhibit is free and open to the public.
