According to the Amick book, George Manter was a real estate investor in Coral Gables, Florida. He purchased the "Princeton Block" from Myron Kaller's group of investors for $500,000 in July 1979, using a $350,000 loan from Summit Bank of Tamarac, Florida.

Manter saw stamps as an underappreciated asset class. However, shortly after the purchase of the block, the IRS changed their regulations regarding inclusion of tangible assets in Keogh or IRA accounts, resulting in a decrease in the enthusiasm of buyers.
