Add a second logo to my header

How can I go about adding a secnd logo to my header. I’ve found loads and loads of tutorials about adding one logo, which I’ve managed to do, but I need to add a second one, so that both appear on all pages. One of the logos needs to sit ranged left and the other ranged right in my header.

Can anyone please let me know how to go about doing this or help with how the header/css code needs to be edited?

Many thanks
