The Gold Seal was the first of the "decal" Duncans. That is the earliest with a decal logo. Decal logos are tough to find in good condition, because they crack with age and flake off, and wear quickly with play.
The Gold Seal Duncans came in a wide array of colors, and several different decal colors. Pictured here is one with Blue in text of the logo, and blue outside border. The Big "G" is still on the logo, but not as profound as on many of the imprinted yo-yos from the same period.
