As I noted in the January Organic Integrity Quarterly post, non-certified operations were a problem for NOP in 2012 and garnered more complaints than certified operations. That said, NOP has been pumping up their organic education resources and they've got one easy way you can help - postcards and / or posters.
The postcards, available for free in pdf, are designed to print double-sided on Avery 5889 (4" x 6") postcard stock, while the posters, also free are made to print on normal sized printer paper. Both the postcard and poster, link to NOP's Is Organic an Option for Me? page, making these a good way to quickly pass out information to business owners you know who may be interested in going organic.
Oh, and if you're looking for postcards specifically focused on consumer awareness, check these postcards out.
