This game is complete in its original box. However, it was originally devised as only a six hole game. The 23 pieces listed on the inside of the box lid are all in the box.  Flags, holes, obstacles, tee signs—everything is made of metal.  Wee Golf was made in Canada by Accessories, Mfg Co of Montreal.  "Golf 1931" is written in old pencil on the top of the box.  That seems to be an accurate date for this set.

You will count only 5 obstacles, which are in read, but the 6th obstacle is the single larger green cup, It is designed to fit up against a wall and has elevated sides that will send the ball off at an angle if the putt is missed.
