What you have looks to be a Lardy set. It was made in France. You will see this design was used in the plastic sets that we call the USCF standard plastic.
That set was not very expensive when new. Of course original ones now bring more money since they have not been produced for quite awhile now.
The pictures look really nice. Your grandchild should get great service and pleasure with this set.
This is the first chess set I got when I was a young boy...bought by my father over 60 years ago in Minnesota. I didn't play much chess as an adult and it has sat in its storage box for decades. Now that I have grandchildren who are deeply into chess, I've started playing again. I am going to give this chess set to one of my grandkids and was wondering if anyone could tell me anything about it. It looks to me like a standard Staunton-type set, and I can't imagine my father having enough money to buy an expensive set, but it still looks pretty good after all this time, and it has no splits or cracks. A couple of the larger, light pieces show a little dark grain striation, but I find that interesting rather than a flaw. The king is 3-11/16" high with a 1-1/2" base. The pieces are nicely weighted and handle well. Is there anything more to know about this set? I'd be interested to know what type of wood it might be; if it is a particular style or just a garden variety Staunton set; and where such chess pieces might have been produced in those times. Thanks.
