IF YA WAS..... a real sign maker, with sign maker programs like COREL, the full version is loaded with clipart. even if you have an older version from 7-12 X3-X5....ALL PREVIOUS VERSIONS of clipart will work in X6 or X7. that is something every shop should have.
also there is another similar graphic/vector program ARTS & LETTERS 8.5 is under $100 and has a bunch of clip art.
getting VECTOR graphics FREE......... is the only joke here....
if you aks where you can BUY SOME....... iam sure there are people here with stacks of cd's plum full of stuff they bought and might be willing to sell it to you)))))
