Sunnyvale Heritage Park Museum has a fundraiser in which (4×8) bricks can be purchased and custom printed. For those who visit the museum, you will notice the courtyard in front of the museum as well as the surrounding wall are adorned with commemorative bricks (walkway) and tiles (walls). Individuals and families honor loved ones or organizations/businesses with their names displayed on the brick/tile surface. New ones are installed once a year, in August.
If you would like to purchase a brick, you can get the information here.
