they are entirely without merit or value

I did a search on ebay for "black velvet painting" on both completed and current listings. Ones of Elvis or other famous people can go as high as $100 or more. Most other ones, e.g. wildlife, go for about $20-$25 (I saw some wolves, fish, etc.)

baby on board
I think it depends of who is the artist? Because some of them are sold in $100 and others in $25 or more!!!
