Sites for clean clip art and pictures

Here are some sites I've discovered that are free and clean.

• Smile land
  
• Antique clip art
• Lisa's Garden
• Here is another one I just found
  

Dolls and Lace clip art

• Retro clip art

I think this one is okey. from what I saw of it but i didn't go through all the pictures.

I'm pretty new on here and would love to hear about what you have discovered for your blog. Please share:)
