The initiator of the campaign is the sister of little Mateusz from Tomaszów Bolesławiecki. Ms. Marzena wrote on Facebook:

Dear all ♥

I am the sister of a wonderful boy with Down syndrome, whose birthday is on April 25 :)

With your help, we would once again like to give Mateusz a present ♥ Mateusz loves opening letters and packages :) so we would like to ask you to send him a birthday card :)

What do you think? Will you help us surprise Mateusz? :)

Would you like to join Ms. Marzena’s campaign? If so, here is the birthday boy’s address:
Mateusz Waśniewski
Tomaszów Bolesławiecki 179
59-720 Raciborowice.
