The best way to assist Abby in verifying the dates the talcum powder was sold is to Confirm that a web site that is selling a 1929 advertisement for the product includes serial-number certificates.
If she bought a sample of the original product from a reputable website or even if she read a rating review of a 1929 advertisement of the product, she would just be relying on the word of those people which would not have passed any peer review and would not have legal value. Besides, if Abby viewed othe products recommended by sponsors, she would be relying on the economic interests of the sponsors and publishers.
The only way to verify it for sure is to check the serial number certificates. These numbers, and the information available in the Official Gazette of the United States Patent Office have legal implications and have undergone governmental scrutiny, which make them a reliable source.
C hope that helped have a good day
