They look like postmarks. That's a date, not time stamp.
In any case, they look like fantasy postmarks rather than originals.
Found this also. Same image.

Labeled vintage poster.
?
also.......
Date of postmark may be timely.
It is highly unlikely that poster is "vintage". Why do you think it is?
The "postmarks" you show all appear to be fantasy items just as JBK has said.
There's more images that I found regarding this item.
Other items, saved from the trash, may be, maybe related to these postmarks found in one site.

just spit balling here.

.The belt buckle is the same in all images. The letter G., George Herman Ruth.
Approval from MLB was not needed as there was no logo images on some documents

You keep calling them "postmarks". If they were authentic baseball pictorial postmarhs from the 1920s they'd be well-documented.
Show us one postally used on an envelope. It's no accident that all those in the first post are free standing and not overlapping a stamp.
Babe Ruth was playing with the Yankees since 1920. Nine years later Boston used a Babe Ruth postmark? And included his little-used real first initial on his belt buckle?
