Taz Cardz asks, "What is a team night sheet?".
They are uncut perforated sheets that were handed out at "NBA HOOPS Nights at NBA arenas across the country. I am not an expert but I think they first started the idea in 1990. There are sparse uncomplete description and checklists located in the BIG Beckett Basketball card Pice Guide. I don't have the latest 14th edition in front of me but in the 13th edition you can find a description for the 90-91 on page 133.
I started collecting them in 1990. Each team was in charge of distribution and usually distibuted the sheets as a game giveaway. This resulted in a lot of the sheets being torm into single cards immediately. The sheets that remained intact were either dinged or creased during the game or the ride home. A smarter distribution method was to distribute after the game. Some teams cut their cards into strips and disributed then on different nights. In Phoenix in 1990 the sheets came attached to cases of pop making mint sheets virtually impossible to find. Other teams let the sponsors distribute them at their respective places of business. Most teams were liberal in their distribution process and other were ultra conservative. In some cases the team really embraced the promotion and several printings with different player and sponsor variations were produced. In 1990/91 while chasing the promotion I found that a few teams were very hard to get. It took 7 years to fill my 90-91 master set. I am not exactly sure it is complete because I've never seen an official checklist. The teams that were very hard to find on 90-91 were the Boston Celtics,Dallas Mavericks,Houston Rockets,LA Lakers(full sheet),Miami Heat,New York Knicks,Philidelphia 76ers(only1sheet),Portland Trailblazers(they cut sheets into strips),Seattle Supersonics(4 diff variations),Utah Jazz(only2sheets), and the Bullets. The Detroit Pistons were originally tought to get but can now be had for a dime a dozen. I found out a couple years ago that the Pistons mistakenly overlooked several cases during the giveaway and several years later several cases were found in the Pistons dumpster.
In subsequent years the teams became more security minded with the sheets as the promotion was quite costly. In 91-92 and 92-93 the sheets were still obtainable in the hobby market but after 1993 most teams are impossible to find. While the promotion continued in most NBA cities, getting a sheet without attending the games became quite a task.
I have over 200 different sheets half of which are not listed in the BIG Beckett Annual BB card price Guide. They are a neat collectable if you can put up with their oddball size. The reason I like them is because they do present a challenge to the collector in that they are out there if you want to dig hard enough to find them. If I were a faster typer I could tell you more but I hopes this helps.
