Now, as the 10th anniversary of the attacks on the World Trade Center approaches, Spall would like to find some of the Illinois school children whose kind gesture made the tough work tolerable.
The children made paper angels which were put on a Christmas tree set up at World Trade Center site. Spall collected them when they fell from the tree during the winter after the attack, and he has kept them along with several other personal mementoes of his work there.
"I hated to see them wet, and on the street," Spall said.
Messages on the backs of the angels read, "Gina Dial, 9, Naperville, IL," "Courtney, Age 10, Naperville, IL," "Hall Family, Glen Ellyn, IL," "Brad, Age 9, Aurora, IL," and "Truesdaler (or Treesdaler) family, Wheaton, IL."
If you can help put Spall in touch with any of these children, please contact ABC7.
