This postcard was postmarked 100 years years ago on July 2, 1909. Although it doesn't say anything about the 4th of July holiday, I would still consider it a 4th of July postcard because of the date it was mailed. This little girl is dressed as Miss Columbia. Although this card does not label her, I have seen a postcard with an identical picture that has "Miss Columbia" printed on the front of the card.It is somewhat of a custom in the U. S. to dress in red, white, and blue on the 4th of July. I remember wearing red and white striped T-shirts and blue shorts when I was a child. More recently, T-shirts with patriotic symbols have been popular for all ages.
My vintage thingies this week are red, white, and blue potholder dresses. Potholder dresses seem to be the most common of the potholders shaped as things. I quit buying the potholder dresses some time ago because I thought I was getting too many. I didn't realize how many I had until I got them out to photograph for my blog. I have other colors of potholder dresses too, but red is definitely the most common.
