Welcome to the forum n/a. James may be right depending on how fine you want the points on the pattern to be. About the smallest bit I would try that with would be a 1/4" diameter, preferably an upcut spiral. The lines are uneven enough that you could do it freehand and would probably look good even if you don't perfectly match the lines on the pattern. Probably the best way to do it (scroll saw, jig saw, or router) would be to have that blown up to the size you want at a copy shop and then glue it down with spray glue or water soluble glue.
Someone I consider a master woodworker once told me that a master woodworker is not someone who never makes mistakes. He is someone who is able to cover them up so that no one can tell.
