The Birds of Your Garden collector plates were the first series to be sponsored by Encyclopedia Britannica. The series was comprised of 10 different plates painted by the artist Kevin Daniel. They were produced in limited edition by the Edward M. Knowles China Company.
The first plate is marked 1984 while the 2nd two are dated 1985.
The above 3 plates are dated 1986.
The Hummingbird plate was issued in 1986 and the last 3 plates of the series was issued in 1987. With the exception of the Cardianal and the Hummingbird plate, these can all be found on my website for sale.
