Button image templates for calendar
===

My program (OS X 10.7) is supposed to have a button that reveals a popover with a graphical date picker. I don't want to have a big button that says "Calendar" on it, but I can't find an NSImage template (https://developer.apple.com/library/mac/#documentation/Cocoa/Reference/ApplicationKit/Classes/nsimage_Class/Reference/Reference.html) that shows a calendar and the unicode 231A (watch) just shows a box inside my button. Any suggestions on something simple I can do with this button so the user understands it's for picking the date?
