Anna, you may be sorry you asked that! I'll give you a short answer before suggesting you check out the numerous tipple references in the forum.
Looks like a ukekele. Has 10 strings, 4 courses, sounds kinda thin and tinny. Was known as "Martin's Folly" around their company. Can be had in better antique and junk stores everywhere. We've got one at Encore Music in Toronto that they can't GIVE away!
Blame Catspaw!
pronounced "Tee-Play".
