[4reals]

I have only dabbled in acquiring one here and there for my Dodgers collection but I would like to gain a little better understanding of these if possible.

They don't have years associated to them because my understanding is that they were ordered over and over again by the players over a number of years but I was wondering, design-wise, how can I identify ones that are earlier or older than others without the use of a postal stamp on back? Is there a way or were they designed based on what the player requested? Also, are the photograph paper ones reprints and not original?

Here are the different ones I've identified. Can someone please help me put them in chronological order if possible and fill in any gaps of variations I may not have listed?

1. Postcard stock - stamp box back with two production lines also on back
2. Postcard stock - NO stamp box on back, ONLY single production line on back
3. Photograph paper - back same as #2
4. Front image plain, photo only
5. Front image with only JM logo in corner
6. Front image with JM logo AND name box
7. Front image with only name box
8. Multiple variations with linen card stock
