I chose this picture from Flickr from the Library of Congress photos. After our very long winter, I am longing for spring and warmth and sunshine, and the flowers made me feel like summer. I am ready to be done with grey snow and cold dampness. Flowers would be welcome right now.
Most of the Library of Congress photos are in black and white. These flowers were in color, making them even more appealing.
I did not know about Creative Commons licensing. After reading about it on Wikipedia, I find it an interesting concept.
