Produced in the 1960s by Dell Plastics out of Brooklyn NY.
This was the only Dell Trickster made without the big D in the middle.
This one is in fair condition. It appears to have some minor discoloration. The seal imprint is faded but readable. Made from two parts of plastic that are pushed together making each half. There seems to be some separation between two of the pieces. You can see it in the picture.
All in all, it's a pretty obscure yo-yo that has a unique look and readable seal.
