The golden anniversary of the Quezon Institute was commemorated on the 1988 seals issued se-tenant showing personalities, the Institute, and places of worship.
"Things Philippines" were the subjects for the 1987 TB seal. Also issued se-tenant, these "Things Philippines" were Calesa, Rice Terraces, Tinikling, Jeepney, Mayon Volcano, Singkil, Moriones, Careta, Ati-Atihan, Itik-Itik, Vinta, Fruits, Noli Me Tangere, Mi Ultimo Adios, Jose Rizal, and Fort Santiago.
Flora and fauna were the subjects for the 1985 TB seal. Issued se-tenant together with reproductions of the 1910 and 1946 TB seals, the featured flora and fauna were Philippine Eagle, Magellan butterfly, Sampaguita flowers, Bangus, and Tamaraw.
The 1978-79 TB seal continues its campaign to phase-out tuberculosis in the barrio.
TB seals used to be sold at post offices nationwide for use on mail posted during the Christmas season. At times the seal receives a postmark especially if this was affixed next to postage stamps.
In 1961 the Christmas seal featured Pandango sa Ilaw. Stamp collectors have adopted seals as part of their collections since they look like postage stamps.
The Philippine Tuberculosis Society issued this Christmas seal in 1947 depicting a profile of President Manuel L. Quezon and a partial view of the Quezon TB Institute. Interestingly, the seal is multicolored -- not like Philippine postage stamps at that time, which were issued in only one or two colors.
