The above link is a discussion of this variety at another website when Burpee first brought it out.
Even if someone paid me I wouldn't buy any tomato seed from Burpee. They used to be a great company but not anymore and made it through bankrupcy to continue existing. Many of us are really mad at them for stealing the names of varieties that are heirlooms and well known, and then doing a simple cross to create a hybrid for which they can get more money for seeds.
The Tye Dye one and Black Perle, or however they spell it, are two examples. The first from Brad Gates Tye Dye one and the second from Black Cherry introduced by TGS as bred by Vince Sapp, now deceased, and former husband of Linda who still runs TGS.
Did I forget to mention that I don't like Burpee? LOL
