Merlin has been collecting pictures and old photographs to put into viewfinders windows to help you to see how things change over the years.  There are 2 viewfinders on each sheet of A4 paper.  

1. Cut out around the dotted lines to make windows.  
2. Out on the trail look out for the building on the left.  
3. Stand so that you can see the view through the open window.
4. Spot the differences.  
5. List your answers on the Trail Quest Sheet.
