Hi Cass, yes I think the companies "Terra Nigra B.V." and "Select Roses B.V." are someway the same, perhaps simply a renaming a few years ago, perhaps an overtaking.

Here is a PDF Document with the whole product series of Terra Nigra (including 'Tineke' in white and 'Grand Prix' in dark red) and some additional infos.

I believe that the company used to be called Select Roses BV at the time they introduced the 'Terra Nigra' rose and others. Later, they changed the name to Terra Nigra due to the success of this one rose. So, introduced by Select Roses, sold by Terra Nigra is not too wrong.
Especially as Select Roses is often encountered in rose literature.
