Dell's Big "D" Returner, No. 600 with one green halve and one red halve; metal axle; pre-printed price of 29 cents. Instead of a hot stamp on the face of the yo-yo, this model used a metallic silver (may have been gold but faded over time to silver) sticker with "Dell's Big Returner" in red; the large "D" is in a teal color.
This model is fairly hard to find new on its stapled bubble blister card. The staples suggests that the yo-yo likely came out between 1961-1963. The Returner was eventually released on a bubble blister that was glued to the card, likely between 1964-1965. This period is around the same time that Duncan began sealing their yo-yos on cards with bubble blisters that were glued to the card face.
