A small object parade

An original notice containing five intentional errors.

The route are marked around the courtyard for the temporary exibition. Helpers must keeps identifying card's with the objects while they are moved between stands. The labels contain information needed for the final return check. Please tell the coordinator immediately if a card becomes separated from its object. The planned route may change if a stand needs moving, so the drawing at the entrance is a guide rather than a garantee.

Proofread the notice. Identify the five errors and write the correct forms. You do not need to rewrite the whole passage.
