Wow, Mischka, thank you for the clarification. I visited Mariseed for the first time after seeing your original post, and followed the link to Bill's Created Heirlooms page which seemed like the right place but I couldn't find anything wrong with it. It's no wonder I didn't see the offending tomatoes, as I now see "Jim Dandy" is hidden among the regular offerings.
It's even more confusing to see this done 'right' and 'wrong' on the same site.
My apologies to Bill Jeffers BTW if my original post sounded like a criticism of the quality of his work - I was only reasoning about the general case and did not mean any specific criticism by posting the link. I just couldn't find anything wrong with it, and judging from the other responses here, we agree on that.
The 'Jim Dandy' is something else altogether.
You are right to post a warning for people who may be taken in.
