this is a very unusual thing to paint on…its about 36 x 25..it is oblong…not square or a rectangle..it can make you dizzy to look at it…its thick wood….it has wood braces across the back..it could have been used to secure a horse or a giraffe, it is so strong…it is not real heavy.. it weighs about 12 pounds…which is not bad for how big it is…i will lose my shirt on the shipping but hey i am ripped with abs so i dont care,…
