I'm working on a set of ads designed to have a social media sort of feel. Generally, these ads have a header and a sub-header on a stock image. The brand has a specific header and body font that must be used on all Powerpoint presentations and websites, but I'm wondering if it's terrible branding-wise if I use different fonts that lend themselves better to the graphic feel of the stock image?
Are there well-known brands that do use multiple fonts in their ads? If anyone could provide some examples that would be fantastic. A few Google searches haven't led to anything much but I'm not sure what search terms to use, either.
Any and all advice appreciated, thanks!
