I am presuming that the Tavern was once known as the Aston Cross Tavern? Here is an entry in the Showell's Dictionary of Birmingham 1885...
Aston Cross Tavern was opened as a licensed house and tea gardens in 1775, the first landlord, Mr Barron, dying in 1792, his widow keeping it until her death in 1817. Of late years it has been a favourite resort of all classes of athletes, though from being so closely built to it has lost much of the attraction which drew our grandfathers to its shady arbours when on country pleasure bent. The park wall extended to the corner of and along the side of Park Lane, opposite the tavern.
If it was not it is still an interesting piece! All the best Peter
