Dave HornishBuried deep in the pages here is a scan of the Obak sheet-I recall it was quite large, maybe almost 200 cards ( I recall 19 columns for some reason but don;t quote me on that). I noticed it when I paged back through the site a couple of years ago, I just can't find it with the search function so it may be in a non-Obak thread.
It bears repeating too that you will never know the full array, your best hope is determining how many different subjects are in a print run.
A 48 card T206 sheet would be quite small-I have to think the size would approach what the packaging was printed on sheet-wise and I believe there are some fairly large uncut tobacco packaging sheets out there that might provide a clue.
