Some popular options include tours of Washington DC, Boston, Philadelphia, and New Orleans. Alternatively, you could also consider purchasing a historical book, such as a biography of a notable figure or a coffee table book featuring images of significant events in history. Additionally, if your friend is into DIY projects, you could consider gifting them a 3D puzzle of a historical landmark or monument.
