Bud, Not Buddy's suitcase symbolizes a life story. In this case the young boy had all hids life possessions in one spot. It gave him a feeling of home away from home. He had his blanket that he used to cover himself up when he was in difficult situations. The flyers were a symbol of a past life story. At the end when we find out who Bud, Not Buddy's mother really was we realize that she must have been following her father with these flyers. All through the story, before I found out the truth I felt sorry for Bud, Not Buddy having to carry and worry about that suitcase. It payed off as it was the final evidence a family needed to put an end to speculation about a missing daughter.
