This would be classified as a "storecard" and collected alongside trade tokens by many, but not all, collectors. The difference between it and a trade token is that this piece is advertising the Baldwin Company's products whereas a trade token was used in place of money in some way. This was probably a give-away (like today's paper business card) or may have been included with a shipment from the company in hopes that the recipient would carry it in his pocket and be reminded about their company and its lines.
This has the appearance to me of a 20th Century piece - I can't tell without a lot of looking how old the A. Baldwin Co. is, but the 1893 New Orleans City Directory shows Albert Baldwin as President of A. Baldwin Co. Ltd. located at 12-22 Camp, corner of Common. After snitching some info from lahistory.org, here's a bio of him:

My guess was that the reference to 1822 was based on the "Keen Kutter" brand of knives, but I see that it didn't go back that far. Don't know where he came up with that date...
