[Get-the-point]

I was at work on saturday and it was a slow day. We were on our way to the last job when I said look a garage sale. This is a big joke between me and my partner as I always haunted him about stopping everytime I saw one in our travels. So on saturday he took me off guard and as I said, "Alright a garage sale" he pulled over and said here ya go man we have nothing to do so have at it. So we all started to look around when I came across these 3 pieces. The first artist is Louise Cazenavette. This piece is beautiful and depicts children in a boat. This piece is titled something close to that. The next 2 were very nice lithographs both signed and numbered one had Alvar signed in pencil on it. The next one had Bordenave signed in pencil as well. I did some research after I see on the back of these authentication certificates. My phone is set up for the internet and I found out that they were listed artists. So I asked the lady if she would take $25 for all 3 and she said she would. I still have no idea if they are worth anything. So I am hoping someone here might be able to possible values to them. Well apparently I cannot post pictures from my phone so when I get back to my puter I will post them....
