Hoof,
Dutch is our webmaster. If you would let him know which labels, specifically, are your altered ones then he will provide credit.
Plus, I thank you for your generous offer to freely share labels with our members. If you would send the .jpeg or .pdf of those so he could put them on our website, you will receive a byline.
The idea being NCOWS is constantly growing, and there are always new members (and non-members) who rediscover the site anew and will want to make use of labels for their own reenacting, too. We are trying to build a one-stop resource for these kind of public domain materials for sharing. Cartridge box labels, food labels, spirit labels, tobacco related, drug and medicine labels, etc. We encourage everyone to please contribute what you can for the enjoyment of all the members.
After I finish each subject article for publication in The Shootist, I send the corresponding digitized label images from samples in my collection to our webmaster to post on the site. Great way of tying our magazine and our website together and providing a useful resource.
