Quick question for the business or lawyerly types:

I decided to make a poster for my guitar teacher for his studio. I took a picture of my Fender Strat leaning up against my Vox amp and then put his logo on the bottom of the picture with a slogan I made up at the top. I did it in photoshop and then had it printed at Costco.

My question is, you can see the Fender logo on the headstock and the Vox logo on the amp. Is it copyright infringement to have these things visible in the photo?? I'm not terribly concerned because it will just be for his small studio but I just want to be sure in case he wants to use the image as a flyer or something.
