Lynn has recently come into possession of a number of hand carved/painted duck decoy's, and framed/matted prints w/stamps. These were her father and brother's who recently passed. I would like to get educated as to their value, so if anyone has an idea where to start, i.e. web sites, etc. please give me a heads up. They also need to be cleaned up, so I'd like to find out what to use to clean them, and maybe more importantly what not to use.
