It depends on what you intend to use it for, and what you paid for it.
Descoware was made in Belgium after WWII and probably before 1965. Nearly perfect pieces are scarce, but there are many well used on eBay all the time.
Crazing, like on yours is common, as is chips in the enamel, discolored or dull interiors, etc. They are perfectly OK to use. I have a number of pieces that are less than perfect, but work fine. Those are the ones I use and don't worry about, because they were cheap. I also collect Copco from the 1950's, but don't cook with them much. Their designs have more personality, to me.
I would check out Descoware on eBay (completed auctions) to see what they go for, and decide whether to return it based on that
