An open house sign has two slats to feed letters of an open house address, date, time, directional arrow, and the like. The open house sign allows potential clients to clearly understand by reading the clear lettering, location and time on the open house as clearly as they are reading the standard sign. The open house sign also allows real estate professionals a clear way to update an open house sign' s address, date and time without wasting paper while presenting a professional look to the public. These signs may also be used for garage sales.
