I, too, received Scott's prints in the mail today. Both are great! The Carousel really outshines the quiet Stone Wall print. They are worth the wait.
I do hope that you are planning on entering a Carousel print in the Labor Day art show I see mentioned on the park website.
I looked the park up because I have a sister (and 91+ year old mother) who live north of DC. I may have to brave the traffic and visit the park/carousel on my next trip down that way. (Living at the end of a dirt road in a very rural area of NH, I am not fond of urban, or even suburban driving.
I'm looking forward to the next round. I made a few test prints on salted-paper this afternoon in my cool basement dim room.
