Monthly Failure Report: January 2018

I plan to start reporting failures at the end of each month, for failures received during the past month, as well as for autograph requests that were sent out over one year ago without a response.  Here's the first iteration of that.

Unsigned Returns:
Dave Parker
Willie Lanier

Return to Sender:
Red Schoendienst
Mariano Duncan
Bill Mazeroski

No Response from January 2017:
Tony Dorsett
DeMarcus Ware
Ezekiel Elliott
