On rare occasion, when I do buy and Exhibit, I generally try to avoid the "Printed in" versions when possible. The "MADE IN" versions are the older ones. Also, for any player who's rookie card(depending on your definition of RC) fell into the 1949 Bowman or Leaf, the "AN EXHIBIT CARD" version make a nice alternative that could technically be considered a 1949 issue.
