Hello Kevin,

Thank you for the response. Sometimes ordinary looking wrappers are also very interesting since one might expect them to have been torn off and thrown away. I like finding these because they are cheap but scarce.

7 May 1873 Yverdon to Paris. Pre-UPU printed matter rate wrapper 16.5 grams.

26 October 1879 Solthurn to Frankfurt. UPU double rate 50-100gms.
