Brian, Very intuitive on your part. Are we talking Russian dogs during the recent Winter Olympics or Babe Ruth? (trust me, I am both a canine and Babe lover).
Otherwise, the '51 Topps Red v Blue back pricing has me curious. Reds really have all the Stars, Blues are almost an afterthought. I guess the Blues were just not as common(?)
The sort of "We have the world's largest..." type of promo: Same as then, same as now.
