The 19th Amendment is a first hand source you can find almost anywhere. This made it possible for women to vote and this was an important factor in the women suffragist movement. The photo on the left is an image of the signed document of the 19th Amendment. On the lower right you can see a political cartoon of a woman struggling to clasp the last few buttons on her dress which represent the final most crucial votes on ratifying the Amendment. This shows (lightly) how much of a struggle passing this Amendment was, yet women were able to push through and "clasp the buttons".
