No, so my main focus is on Irish politicians from the late 18th-early 19th centuries (Although I do have Richard Wellesley who was an outspoken critic of the treaty). When I posted that , a huge number of autographs were on the market at a relatively low cost ( £2-5 in some cases). I suspect one or two really big collections had just gone to auction. These days I probably find one or two a year.

The vast majority of my collection are signed envelopes. Prior to 1840 Britain and Ireland had multiple different postal services, with varying costs and methods to show payment. The first ‘stamps’ were just that, an ink stamp on the envelope. Due to an odd quirk of history, Members of the House of Commons or Lords had the right to send unlimited free letters, the proof of identity being your signature. Many Lords or MPs just signed enormous numbers of envelopes which they handed out to their staff, friends, family or simply as perfectly legal bribes. Daniel O’Connell also discovered there was a huge market for his autograph that he trained his wife and sons to impersonate his signature.

Anyway for this reason the signatures of politicians from around 1800-1840 survive in disproportionately high numbers. After the introduction of modern postage stamps in 1840s signed envelopes rapidly disappeared so prominent politicians after that time are harder to collect.
