cmokingI got the info about the Sports Kings being printed and distributed in 1934 in the recent Mile High auction where they auctioned off the copyright cards and copyright registration cards of the Sports Kings set. Here's the link.
Sports Kings copyright cards in Mile High auction
Here is a selected quote from their description:
"The official affidavit received date (Feb 28, 1934) is found stamped on the back of the Library of Congress stamped Sports Kings card but the publication date is only on the Copyright card. This date is January 5, 1934 which is found on each of the 1934 Sport Kings Goudey patent cards. "
Here is a link to a scan where you can see the #2 Babe Ruth card's copyright registration card with the date of publication as Jan 5, 1934
