Is this a baseball glove or a boxing glove?

The flask bottle above sold on eBay August 27th for $231.67, link above...It was advertised as follows:

rare 1800s BASEBALL GLOVE Whiskey FLASK BOTTLE ,antique figural OLD

Question...is that a baseball glove or a boxing glove?...to me it looks like a boxing glove...

I did a feature on a silver boxing glove flask in March 2010 that looks remarkably similar, link above

It looks almost identical to the silver boxing flask, so I would agree with you. If it is meant to be baseball, it is a poor depiction of a mitt. What throws me are the fingers, as I don't think boxing gloves had finger separations inside - but I suppose that is meant to just show the outline of fingers/hand inside the boxing glove, and not imply there are finger separations inside the glove.

I have seen antique/vintage boxing gloves with these finger separations so yes this flask very well could be a boxing glove
