How do you get a Green Day Class Of 13 decal on your guitar?

To get a Green Day Class of 13 decal on your guitar, you can either purchase a pre-made decal from an online retailer or create your own using vinyl decal paper. If you choose to make it yourself, design the decal using graphic design software, print it on the vinyl paper, and carefully cut it out. After that, clean the area of your guitar where you want to apply the decal, peel off the backing, and stick it on, smoothing out any bubbles. Ensure it's securely attached to avoid peeling over time.
