I was browsing thru my local "library" (Barnes & Noble) and came across some Dover books that might be of value to anyone looking for older specific clip art. You may have seen them elsewhere too - usually in a turntable type of display probably near the computer graphics section.
Many very unusual titles from angel illustrations thru a number of celtic designs to posters from WW1 & WW2. The accompanying cd is supposed to contain all the designs in the associated book. They ain't cheap - but if you have a specialized need you might find something here not easily found elsewhere.
If nothing else - it's a kick to just browse the available titles. http://store.doverpublications.com/b...--cd-rom-.html
or just go to the doverpublications.com site and search for "electronic clip art"
Enjoy the browsing
