To hold the truck in I started with a flat base and created cardboard hooks that hold the axles front and rear.
Painting and graphics were done simply with stick on letters to mask the white and then masking tape to mask the red after the brown had been sprayed. I may detail around the triangle in white (which I could have masked eariler but didn't know if I wanted to at the time) I added for that custom touch some arrows that point out the "features" of the toy. Vintage toys sometimes had these little identifiers.
Well there you have it! My take on the retro box for a Tonka Mighty Dump truck. Making the box was almost as fun as restoring the truck!
