@ptsandstampex Far and away, the most important meeting at GASS25.

[Mark A. Butterline @ButterlineMark]

Always great to talk with Suzanne Rae of @ptsandstampex. She is a great asset to organized philately. 🙂 #stamps #philately https://t.co/SpJVHjQUfb

[The PTS & Stampex International @ptsandstampex]

The PTS’s Suzanne caught up with Mark Butterline of the @Boston2026Expo team today to share ideas on how we can boost the experience for our Members at the show - from customs to promotions to first dates (!) to stand sales and dealer liaisons and booth holder treats!

We are so excited about this show and how it is shaping up to promote every aspect of philately. From beginner level activities to world class exhibitions.

If you’re doing Boston26 and aren’t yet a PTS Member, why not apply now to ensure you get our full support and promotional package (as well as all of the other benefits which come from PTS Membership). ➡️ https://t.co/1gc8MOVCHI
