"A Good Story" Yuengling Beer Advertising Oil Painting

I enjoyed this painting in my grandmother's kitchen since I was able to remember it. Now I am proud to finally own it, good memories.
Grandma was a school teacher and church lady. I always wondered why she would have such a sinful painting in the kitchen.
It's not a print and it is painted on hard canvas unsigned on front. Measures 15 1/2 x 27 1/2" including the wooden frame.
It turns out to be a Yuengling beer advertisement original oil painting.
