This logo is still used on several Frito-Lay trucks. This logo is also still used by Lay's Deli Style Original Potato Chips. Also, this logo is still used on the lids for the Lay's Stax cans.
This logo was introduced in late 2003. The Lay's text's shadow became gray gradient, and the word "brand" and the registered trademark sign inside the red part had been turned white. The logo was also turned in 20 angles in a 3D perspective sort of way.
In 2007, the logo turned 3 dimensional while Lay's started a new font and the gold band was added.
