I fell head over heels for these. They're very nicely done and a large size, plus they come as a set. Luckily for me I had my son (aka 'Eagle Eye') along on my thrifting trip yesterday. I picked up the one with the swans and thought for about 2 seconds whether I was going to purchase it or not, and while I was doing that he noticed the other one in the bin. Sold! (For $6 each.)
I've started collecting vintage landscape paintings to decorate the hallway up at the cabin. I saw the idea in some magazine where a lady did the same thing- just filled the stairway floor to ceiling with paint by numbers of horses. It turned out great, and I'm envisioning the same up there but with landscapes.
I don't know what it is about p-b-n's, but I have always loved them. Maybe it's the thought of an amateur trying so hard to get it right or the definition of the lines of color, but I have a bunch of them. I could very easily cover a whole wall with them and I just might!
