I have been working on tweaking my master for the early 1970s Thunderbolt decal.
Without an actual decal to work with, and without knowing the "THUNDERBOLT" font, I have come up with my best idea as to what the decal should look like.
I am soliciting constructive ideas pertaining to how the artwork can be improved or made more authentic. Within reason and within my rudimentary painting abilities, I will attempt to incorporate any significant suggestions so that our restorations of Thunderbolt sirens from this era can be made as faithful as possible to their factory appearance.
The full size decal can be viewed by clicking on the image and selecting the "original" size from the available image sizes.
