Thanks for the kind words, Al and Larry. A slight correction here--Topps 1968 Milton Bradley is not a set of 76 with one variation but rather a set of 77 with no variations. To be technical, a variation exists when a card is corrected. These two checklist cards are separate and distinct, and were not corrected. The tan broad mesh ("burlap") CL #107 MB card is at the far left end of a row of eleven cards, as is the brown fine mesh ("mesh") CL MB. The burlap CL 107 is adjacent to a Don Wilson #77 card and the mesh CL 107 is adjacent to a Dodgers Team #168 in both the regular and MB series. For both the regular and MB cards, a severe left off center checklist card with a large right side border can be matched with the extreme left of a Wilson or Dodgers team card (with good eyes and a magnifying glass!). The crosshatch has a distinct pattern.
In the full MB set, four rows of BB burlap mesh 1st series cards (including the 107 CL) and three rows of BB mesh cards (44 + 33) as well as 33 1967 Topps FB cards and 22 Hot Rod cards made up a half sheet of 132 cards. Huggins and Scott has a very nice set of all 77 BB cards coming up in their April 2013 auction with more information on the set.

Both the Colavito cards like the two separate MB checklists are at the very left of a row, with this off centering you can see both have a white left border, as do badly right off centered CL cards. The MB is pictured first, with a bottom border (top of a hot rod or football card) that is unique to the MB cards.
The third picture shows side by side, MB with the yellow back is on the left, the regular card is on the right. Shadowing isn't great here but under good light there clearly is a distinct color difference.
