Let's say I run an organization called Shoesies-For-Kids.
I know about this really cool art company online. They have some awesome pictures of shoes and I contact them with a "Hey there! I love your shoe pictures. Could I get permission to use pictures of your red shoes?"
They email me back with "Well, sorry we aren't giving permission to anyone to use pictures of our red shoes anymore. However, we are giving permission to use our blue shoes. Would you like a copyright permissions document?"
I respond back, "Yeah! That would be awesome can I get that permissions doc"
"Sure" they email back "Here ya go!"
And here is how the permissions doc reads.
"Blah blah blah this doc gives permission blah blah blah, you may use pictures of our blue, black, purple, pink, red, orange, yellow, and white shoes."
I really really like the red shoes picture. Even tho its obvious they don't want to give permission for their red shoes, the copyright document says we can use the red shoe picture. Maybe they just haven't updated their copyright doc in awhile? So whats the deal here? What is some legal text I could look at to understand how this scenario works legally?
