This is a vintage set of four (4) hard plastic advertising coasters.  These coasters were made in the USA by Ritepoint.  Coasters are new old stock in original packaging.  Packaging is clean and bright and in excellent condition.   These advertise for "The Sexton's - The Biggest Bullshippers in Hooker County - Mullen, Nebr."  They are not dated, but lack a zip code, and appear to be 1950-1960.   Packaging measures 3-1/2" x 3-1/2" x 1-1/4".  There are no off odors.
