clip art and art work

where can I find art work of pizza and such, that I can blow up for posters and signage to about 2ft by 3ft WITHOUT losing its quality?

maybe here, and there were more on Goggle search … -223690178[microsoft%20clip%20art%20images]Broad

hope this helps,
To enlarge photos (bitmaps) to that size you will need a good size image so you will likely need the XXL size…Illustrations (vector) will likely scale to that size with no problems…Good luck
