Help with finding Dan Whelan auto
 

Can anyone tell me if they know where I can get a Dan Whelan autograph? He was the trainer for several years with the Pirates (1960) as well as later with the Knicks. There's a signed photo on the Bay cheap but the writing is faint. Looking for a 3x5 or something I can mat the auto with my other Pirates.
Any help would be appreciated.
Thanks,
Mike
