fkwBTW if anyone cares. the postcards are from 1932 not 1929, and the W517 is from 1931-32, and the Mini's are 1932.
The rare 4-in-1 postcards like the one above (3 different are known) are listed in the 2006 SCD Catalog as from "1929" (page 139). But as Adam noted on his webpage and the teams the players are listed with, they were issued sometime after April 1932.
Critz pictured with NY Giants....... traded to New York May 21, 1930
O'Doul pictured with Brooklyn....... traded to Brooklyn Oct. 14, 1930
Kamm pictured with Cleveland........ traded to Cleveland May 17, 1931
Shires pictured with Boston NL......... played with Boston only in 1932
Donohue pictured with Boston AL....... played with Boston AL only 4 games in 1932 (also mispelled "Donahue")
Now my last question, does anyone have W517 Mini's where these 5 players are listed with a different team that noted above??? 
Kamm W517 Chicago AL...... W517 Mini Cleveland AL
Shires W517 Chicago AL....... W517 Mini Boston NL (airbrushed to "Boston" on uniform).
Donohue W517 Cincinnati NL...... W517 Mini Boston AL
Critz W517 Cincinnati NL......... W517 Mini NY NL
So the true date of issue....
W517 1931-32 (4 cards have team changes between Oct.1930-32)
W517 Mini's 1932
Postcard 1932
