Alpha Sign Co. occupies a storefront space that's set back from Ventura Boulevard; the entrance is actually on Matilija Avenue. Once in the vicinity of this friendly shop, it's hard to miss, thanks to the large fighter-plane mural that's painted on the facade. The unofficial motto here is "signs—any kind," and Alpha offers exactly that: any and every sort of sign. For business or personal applications, Alpha can craft the necessary custom sign. Alpha offers installation services, too.
