For anyone interested in Press Sheets (or imperforate stamps) I find it interesting that you can now pre-order the 21-cent Abraham Lincoln Press Sheet from the USPS store. The format is only 1x3 so there's a total of only 60 stamps without die cuts, at a modest price of only $12.60.
It seems to me this could make for a lot of interesting covers, since a pair of the Lincoln stamps, coupled with 7-cents additional postage, would make up the first-class mail rate and could allow a lot of potential collectors to gain legitimately used imperforate pairs on cover without a major investment in large quantity Press Sheets.
