<prompt> Human: When I was a kid my uncle bought me stocks in Mattel pretty sure as a birthday present... Not a lot but just as a gesture. Problem is I dont have any paperwork anf my uncle isnt around any more to ask. Is there any way of tracking down those stocks and claiming them?  <response>: You could try Mattel investor relations I would call the transfer agent Computershare and see if they can find anything in their records.
