The words of the poem on this card are:
The time is gone for argument, you've heard the Leader's call,
There's a burden we must carry, there's a service for us all.
From Portland Maine to Oregon, the call has now been sent,
Forget the past and get in line, stand by the President.
Apparently there is more to this poem. I saw a nearly identical postcard with the same title, author and number 2185. Only the words were different:
McKinley called in Ninety-eight, Old Abe in Sixty-one,
And years before they heard the call of Grand Old Washington,
We'll answer now as they did then in accents loud and long,
We are coming Woodrow Wilson, a hundred million strong.
