I have a regular client whose art work, logo and marketing collateral were set using Myriad Pro. I hasten to add NOT by me. This company have now fallen out with their original design agency but need me to reset art work and adverts etc using their corporate image. Now they are adamant that the main font used is Myriad Pro (regular and Black). But I really don't think it is. It's very VERY similar, barely any difference, but the t's and q's are very slightly different and it seems condensed very slightly to me. I have tried all the different Myriad typefaces, but it's just not 100%. As it's so close, I was wondering if ever the font's change slightly?
