I have a certificate that I am designing.

Excuse the inconsistent text alignment. At the bottom, I have two logos. The red one is about twice as tall and half as long as the blue one. I am attempting to align them in the bottom corners in an aesthetically pleasing way. Currently, their bottom corners are aligned to the bottom margin corners of the page. However, Logo2 encroaches rather significantly on the signature lines, and I cannot shrink the logos without making them appear comically small.
What are best practices for aligning multiple logos of significantly different sizes/proportions?
