Main Hallway!

My school's  main hallway bulletin boards are famed by the themes selected. Specially  for the back to school class lists. Everybody knows Rosita, a lady who works at the school administration and the person responsible for "dressing up" the bulletins. She takes pride of the artwork put on there. The school community always expect something new, spectacular. The themes always remain a "secret"  until the calendar marks "the day". She has a team that always help her. She assigns them part of the theme, gives them an idea of what she would like to see there, and then...magic comes on. Every teacher starts creating, drawing, cutting, pasting... their vision from her idea. Time comes to put all together and ...Voila!
