Just recently on Ebay, one seller ($1gem) listed four Walter Johnson signed postcards. 

Ebay seller $1gem listed four Walter Johnson signed postcards.  One already sold for $487.00.  The other three are presently (May 21, 2012) listed on Ebay.

Below are photographs of all four Walter Johnson signed postcards.  All four were authenticated by Drew Max, who calls himself a Forensic Document Examiner (FDE).  I also found it interesting that all four LOAs from Drew Max are dated Jan. 6, 2012.

In my opinion, none of the Walter Johnson signed postcards are authentic.  In my opinion, these are pathetic attempts to emulate Walter Johnson's signature.   I would like to know what type of forensic examinations Drew Max performed to come to the conclusion that the four Walter Johnson signed postcards are authentic?  Like a friend of mine commented "What a waste of nice postcards."

Here are the four Walter Johnson signed postcards which, in my opinion, are not authentic.

I found it interesting that all four LOAs are dated Jan. 6, 2012.

Here are close-ups of all four signatures.
