There seems to be no break in collectors' desires for Sammy Sosa items. Postal officials in Chicago increased their order for the limited editor souvenir envelope with Sosa's likeness on it. The order was increased to 50,000 late last week. The envelopes sell for $10 each and there are a limited number of envelopes in a framed plaque that are available for $70 each. Officials say the envelopes are meant to be collector items and not for routine mailings.
