Testing Family Artifacts to Obtain DNA Evidence for Genealogical Research

My DNA cousin, Jenny Chronopoulos, from Melbourne Australia just sent me these two very interesting articles.

Rumor has it that in January My Heritage will begin offering testing of stamps, envelopes, etc. to recapture DNA from deceased parents, grandparents.  I cannot find an official statement from My Heritage.

Apparently an Australian company is already doing the testing (referenced in articles.below).

PERSONAL NOTE:  I have letters from some of my grandparents siblings and would love to do this, but will wait until the price becomes more reasonable.
