I do, actually! This was located where the LA Furniture Mart is now, which would be Washington and Hill.
I know this because I went to the LA Auto Show recently (I go every year) and they actually had a very interesting display that showed the history of the LA Auto Show, from its beginnings to modern times. It's been going on for over 100 years now.
After this fire, whatever cars were left were displayed at the Shrine Expo Center. There were pictures of 1920s cars being displayed at the Shrine Expo Center.
