This was an interesting project I got to work on.  The owner had two separate businesses, but wanted to run them alongside each other with both logos needing to look like they fit together.  

I created a logo that incorporated a “location” pin as well as the transport and construction elements for both businesses.  We differentiated between them with subtle differences, but also with different colours.

This worked very well on the submarks, stationery and the merchandise mock-ups I supplied.
