The Baseball Card Adventures is a book series is written by Dan Gutman. So far there are 7 books in the series.
The books feature a boy, Joe Stoshack, who can travel through time when he touches baseball cards. When he holds a baseballcard, he is transported to the year that card was made and somewhere near the ballplayer on the card. Later he discovers that this power also works on very old photographs. He tries to use this power wisely, and he changes history several times, though in ways not intended.
