Searching for a high-res scan of a pair of wicked cat eyes. 10ft. wide if possible. If you supply, I'll consider giving you a grilled cheese sandwich.
10ft. ? depends how big your pixels are they could be 10ft. each.
It's needed for a 30"x120" banner. Full size at 100dpi would do it.
10 feet at 100dpi = 12000 pixels, which is too much for this board
