So, my student union asked me to design a logo and I've just finished it, sent it to them and their ready to print it. However, I dunno how I've done it, but the logo I've made looks remarkably like a royalty free image that you're able to purchase. It's not exact, but it's close enough. The logo will only be printed on flyers and posters around my university here in the UK. I'm wondering if whether I should tell them NOT to print it and redo the whole thing? Thanks. For the record, I didn't copy the image. The only thing I can think what I've done is that I've seen the royalty free image before and have recreated it, more or less, without realising.
