This card is: XM-53-1466, Bertrand Boisse, Sherbrooke, Quebec, Canada. These cards are Citizens Band Radio/Ham Radio ID cards. I purchased them at an auction thinking they were post cards (some are made that way). Those that came in envelopes and are postmarked are all in the mid 1960's, so I believe they are all from that time period. I will mail them in a plastic bag, reinforced with light cardboard, in a standard envelope. Shipping is free in the USA. International shipping is done by weight/location. Please feel free to ask any questions. Thank you for looking at my listings, I hope you have a great day!! CANADIAN shoppers, this can be mailed as a regular letter with out delivery confirmation or tracking for just $1.50. Purchase item and request invoice before paying and let me know this is what you want, and I will adjust the shipping cost accordingly. Thank you for looking at my listings!!
