It has already been discussed elsewhere, but I'll throw in my guesses about this here. After looking at the photos of the bezel/surrounding area of the monitor, it reminds me of these two games with some design similarities.
Unsure if American Video Games could be related to World Wide Video Enterprises even though both were in southern California region at the time during 1970s. Space Age Pin Ball could have also been made by either company, but either no advertising flyers were printed or if any did exist, they have yet to be found. The Space Age Pin Ball cab design just seems to be pointing to either of the two companies that once existed.
With this in mind, it somewhat reminds me of one of the moments where Albert Finney's character utters "....there are too many clues..." while conducting crime scene investigation in the train cabin room. The comment is said after this youtube clip scene iirc. The 1974 film version will always be the best version imo. Finney, Lauren Bacall, Martin Balsam, Sean Connery, Anthony Perkins did flawless work in this movie and also Richard Widmark even though his role was limited.
