Good advice. I’m a bit concerned about my experience as it is not focused, from exhibition design to graphic design. I think it might be best to initially approach them for a full time position, and if I get a rejection (or don’t get a reply) then I could follow up and say that I’d also be interested in an internship. I could mention it in the same email as you suggest Ralphzoontjens, but I think that it could backfire in certain circumstances.
