The following are SFO Museum Aviation Collection object images whose mathematical representations are similar to this image. These representations are referred to as vector embeddings and were derived using a series of different machine-learning models.

As such these objects are included because they are generally similar in nature, or spirit, and as a way to help you discover things in our collection which you might have otherwise missed.
