Please ID this bottle

I have a small bottle I'd like someone to help me with. In the center of the
spade is a large "A" with the word ACE underneath. The bottom of the bottle
has 3 1/2 OZ and 3-15 on it. I would like to know what this bottle held and
an estimate of what time period this is from. Below is a link to a photo of
the bottle.

Thanks in advance for any help.
