A year or so ago, my dad and I visited the National World War I Museum. It was a great experience and I really enjoyed seeing all the neat artifacts from the first World War. In the gift shop they had these cool postcards recreating the popular military themed posters of the time. Since I collect postcards, these were a must buy. I really like the art on these beauties.
They even had this cool WWII era Marine postcard.
Even though these are fairly new postcards, they're some of the favorite ones in my collection. It capped off a great museum visit. If you're ever in the Kansas City area, check out the museum. You won't be disappointed.
