Bally did want to call this game The Beatles for the history lesson but couldn't for obvious reasons.
Herb Silvers in the US did reproduce the backglass a few years ago as The Beatles
IMO - top shelp game from the late 1960s.
No it isn't the only one in Australia as the eBay post - I know of 2 others here and one sold for around AUS$750 on eBay about 2 years ago
