Pimpernel British Heritage drink coasters Scenes of Bath boxed set of 6 mint vintage hc3333

This boxed set of Pimpernel drink coasters are part of the British Heritage series and feature scenes of Bath, England. The set of 6 coasters is boxed and shrink wrapped thus never used. The scenes are from etchings. They are identified but too small for me to read.
Pimpernel coasters and placemats are heat resistant to 160 degrees Fahrenheit or 72 degrees Celsius. They are alcohol resistant and cork backed to protect table tops.
They are 4 inches square.
