Phineas and Ferb Electric Guitar Toy, NIB, 

This guitar is the "Rock" guitar.

Not acoustic styled and not really electric either. 

No actual strings. 

There are buttons and knobs, so it's more like a kids "key-tar" 

(But see the pictures! There is not a keyboard either!)

Slight tear on the front of the box, see photo.

From the personal collection of Swampy Marsh, co-creator of the Phineas and Ferb TV show. 

Box is signed by Swampy Marsh! (see photo). 

Portion of proceeds to benefit A Walk On Water charity!
