The Foundry of the Future Mural is on the wall outside the AB&I Foundry on San Leandro Street. It has a patriotic theme and shows the history of the company, which dates back to 1906. The mural was painted by Jean Bidwell.
The mural is 253-feet long, eight-feet high and 2,026 square feet! More pictures here and here. Here is a blog post about the history of the mural which was painted in 2013 (?). From the blog: The mural depicts AB&I founder Joseph Boscacci "making ornamental castings for the city and the foundry’s work on behalf of the nation during World War II. Later images illustrate AB&I’s pride in its city and neighborhood, with iconic renderings of the Oakland Zoo, the Oakland Raiders football team, Fox Theater and the Christ of the King Cathedral at Lake Merritt. The richly detailed mural also honors team members who have worked at AB&I across its history."
