The Herbert Rouse designed booth was renovated over 500 man-hours and now takes pride of place outside the Merseytravel's Tunnel HQ, Georges Dock Building.
Chair of Merseytravel, Councillor Mark Dowd, said: "This was a piece of history that almost slipped from our grasp. Now we are proud to give it back to the city."
The booth, one out of four remaining originals used at Old Haymarket, was sold to Haydock Racecourse in 1963 where it was used to sell Tote cards until the mid 1980's.
It was given to a scrap yard when it started to leak and fall apart but was later rescued.
The booth was moved to Birkenhead where restoration specialists Tarin Engineering began the restoration process. Everything was stripped down and sprayed Mersey Tunnel green. Then identical cast aluminium and bronze panels were created, a new floor and roof was built, new windows and safety glass installed and the original brass switches were also refurbished and reinstated.
Now placed at the North Plaza of George's Dock Building, the booth will be present at the opening of the first Mersey Tunnel.
