About a year ago when starting out on graphic design in school I started doing a bit of free work (something I'm not doing any longer) for a 'client' here and there.
For this one client I provided a logo and some other branding for free, but only for screen usage.
He recently asked me for a print version of the logo to print it on tshirts and when I stated that that would cost him a small fee he backed off.
But I have the feeling he is still going to print it either way (probably with the screen version).
Now I came to the conclusion it was stupid to not agree on some kind of contract or agreement, but the work I provided then was only for screen usage and I would like a cut or one time fee on any work that is being put on tshirts & merchandising.
What are my options here? Is this still protected as my work under copyright when he decides to publish it either way, and can I still take action when he does?
Would it be wise to send a contract now or have I just lost the thing and is he free to do whatever he wants and to print it on merchandising without my consent and paying me?
I couldn't find anything regarding copyrights on a free work on the web so I resorted to StackExchange. Thanks in advance.
