Hi, Toshi -
I'm very glad to see you having so much fun, with a renewed interest in stamps. Being able to share this with Ezra really makes it all the more enjoyable.
My brother in law turned 65 in April, he is a member of Ducks Unlimited, has duck stamps going back for many years. Easy to know what he wants for any gift, the stamps are a big hit.
For Christmas my wife and her Mom put together a leather bound album of his stamps and things related, his wife says he regularly spends our rainy Oregon winter evenings by the fireplace, enjoying the art work.
