This box of puzzles is a nostalgic piece from the past.  It's probably the forerunner of similar plastic boxed puzzles on the market.   There is a stamped on wording on the back side of the box which looks like "Germany"  The box is made of wood and has paper glued onto it.  There is a small latch on the front of the box. The box had fallen apart in the back and a piece of green tape was used to hold it together.  The paper is coming off in areas.  The entire box will need regluing.

Inside there are 12 wooden blocks with lithographs of 6 different animals glued onto them.  The theme is farm animals.  There are 5 pictures plus the picture on the cover of the box which are key sheets for each puzzle.   

The box measures 8" x 6 1/4" x 2".
