I know according to most lists that Marquard's rookies fall into the year 1908. One of which is a minor league issue. One is the Hall's Studio Giants Cabinet, and the other is the E91B which is designated between the years 1908-10.

Now given the fact that Marquard only played one game in 1908, would it be safe to assume that there was not a E91B of him produced in 1908? Also, would it be unreasonable to guess that the Hall's Studio cabinets maybe were produced over a couple of years, or maybe 1909, rather than 1908? If so, would it be reasonable to treat any 1909 card of Marquard as his Major League rookie card? More specifically, I'm referring to the 150 series t206's...
