These are 18" x 24" die stamped and screen printed reproduction De Tomaso Automobili signs. They weigh ~6 lbs packaged, but you don't have to worry about size and weight as priority mail shipping is included within the contiguous US.
Cost is $85, PM for email address and payment details.
The original thread is here with feedback on the signs from purchasers, I have sold well over 150 to date, shipped all over the World;
Given recent discussion on advertisers and true to my own suggestion, I will donate $10 from each sale to the PI forum.
