(White House photo)

WASHINGTON--President Obama--with no fanfare--averted a default by signing the debt-ceiling bill into law on Tuesday.

Noteworthy in the photo of the signing the White House released: Unlike other bill signings, the president was pictured alone, not surrounded by the House and Senate lawmakers who were pivotal in passing the compromise legislation.

Also noted: Obama was signing with multiple pens--you can see them in the picture--so someone may be getting a souvenir.

What Obama signed:

S. 365, the "Budget Control Act of 2011," which provides for authority to increase the public debt limit by between $2.1 trillion and $2.4 trillion; establishes discretionary spending limits for FYs 2012-2021; requires the House and Senate to each vote on passage of a balanced budget amendment to the Constitution; and establishes a congressional Joint Select Committee on Deficit Reduction.
