Glove Identification help needed
 

Calling all glove experts; could you tell me the era and going price of this glove? Markings say professional model. MY brother who lives out of state and doesn't collect picked this up at a yard sale. I just want to let him know what he has.

I personally would say 30s 40s

Thanks for the information.

What would be a good asking price? My brother rents a booth at an antique mall and would like to put this glove up for sale.

Can you post a photo of the back of the Mitt?
