There were 2 printings. 
 
The first printing were numbered 1-24.  
These cards have a fold out stand on the back so each card 
could be displayed like a picture in a frame. 

The second printing was for all 48 cards.  
These did not have the fold out stand.  

The album was probably made for the 2nd printing since the cards 
with the back stand would be difficult to mount in the album.
 
There are also some color differences in the numbers and names.    
Some of the numbers are in red and some of the names are in red.  
If a card has the number in red, it is always in red.  
If a card has the  name in blue, it is always in blue.
