Ripple Grove Press

According to their website: "We are a children's picture book publisher. We are looking for picture driven stories for children aged 2-6. Please do not send early readers, middle grade, or YA manuscripts. No religious or holiday themed stories. We want something unique, sweet, funny, touching, offbeat, colorful, charming, different, creative."

They also have a facebook page where they sometimes post how many submissions they have received. No I'm not going to tell you the number. You'll have to go look it up :)
