Hi Nicole -- thanks for posting to History Hub!
The petition you point to is actually only the one page -- there are no additional pages or signatures. However, it was part of a larger petition campaign.
There are many, many woman suffrage petitions amongst the records of the U.S. Senate and the U.S. House of Representatives. You can find information on them in the National Archives Catalog -- for example, see the file unit for House Judiciary Committee petitions for the 39th Congress.
You might find specific reference to the petition you're looking through through the Congressional Record and its predecessor publications. They are freely available online through A Century of Lawmaking and GovInfo.
Records of Congress are held by the Center for Legislative Archives, a unit within the National Archives. I'd recommend emailing email@example.com for more information on identifying a specific petition.
