First off, you should not be posting comments in the middle of someone else's comments. It disrupts the flow of who is saying what and may be thought of as vandalism.
No you have a biased idea that the be all and end all of baseball cards is those of the United States, which again reflects the almost defalult bias of Wikipedia to be American centred. I spent a lot of time in the UK and my mother is a Mancunian, so I am ever aware of this bias. I am not angry at you, but I am pointing out a fundamental flaw of the article, it is not written in a global context and it is not written for someone who knows little to nothing about baseball cards. 

Of the top of my head, here is what needs to be done
 Have more people giving input on article content, perferably some non-Americans
 Internationalize the article.
 Split off the history of American baseball cards into a Baseball cards in the United States article and have a brief summary of it on the baseball card page

 Return the representative type photo showing various examples. (done)
 Make sure the article is written layman's terms.
