Underground Wackys Variations series 2.
Puzzle 1. There is a second puzzle "Muleburro", but I don't have that one. From the puzzle above you can tell that these are a little sexier in the art.
The wrapper (BTW: same pic for all of the wrappers, just a different color).
Here is the checklist. Again, and for all of the series just 9 cards per set. There are white backs, tan backs, red & black ludlows including the doubles which also come horizontal and vertical, and lastly the quads.
Hope you enjoyed these.
