W.r.t. copyright, I will assume that you correctly determined that copyright in the particular article has expired, therefore you can legally copy and distribute said content without violating copyright law. There is a tiny chance that there are derivative creative add-ons that are still protected (new artwork), but that is unlikely from a newspaper archive.
However, you might be in breach of contract with the archival service. I assume access via Newspaper Archives: here is your contract with them. First, they define The Services:
The Services includes the software, apps, web interface, and content
offered in connection with the software, documentation, and online
tools, whether they are accessed through the use of a mobile device,
computer, or other method (individually and together, the “Services”).
You agree to pay them money to access The Services. §3 states what your license is and how you can use it, pertinent prohibitions underlined.
Company hereby grants you, subject to your compliance with this
Agreement, a limited non-exclusive, non-sublicensable,
non-transferable, license to use the Services. You may not download
any portion of the Services or use of any Services other than for the
purposes described in this Agreement or an Order Form. You may not
use any data mining, robots, or similar data gathering tools or
otherwise exploit your access to the Services for any commercial
purpose, except as you provide professional genealogical services to
third parties on an individual basis. You may not use any of the
trademarks, logos, or other proprietary graphics without express
written permission, which may denied in Company’s absolute discretion.
Company’s logos and product and service names are trademarks of
Company. All other trademarks appearing on the website or in
connection with the Services are trademarks of their respective
owners, and our reference to them does not imply or indicate any
approval or endorsement by their owners unless such approval or
endorsement is expressly made.
Content is part of Services, but there is also a section on Content, §6, which says
Our Content belongs solely to us, even when it is in the public
domain. You may use Our Content only for your own personal
non-commercial purposes (except as you provide professional
genealogical services to third parties on an individual basis). You
agree that you will not redistribute or sell any portion of Our
Content or remove any proprietary notices or World Archive branding
from any of Our Content that you download or print.
On the face of it, you are in breach of contract by copying and distributing the content that they hold. Therefore, you can end up getting sued in Utah courts. After proving that you broke the contract thus you are liable, the company would need to establish what the damages are, that is, how much revenue did they lose from your prohibited action? It might be $10,000 or it might be $1, that's a very fact-intensive determination.
