The DeGrazia print and original painting market is a bit flat right now.
Here is a link for you to a signed print of children in a circle (which may be the same as your image) that recently sold for $24.99:
If the signature is executed by hand, your print can sell for up to $200. If the signature is "in plate" or printed as well the entire picture, then the sale value will be $25 - $40.
